Module levana_perpswap_cosmos_msg::prelude

Convenience prelude module.

This reexports commonly used identifiers for use by contracts and tools.

Re-exports

• pub use crate::contracts::factory::entry::ExecuteMsg as FactoryExecuteMsg;
• pub use crate::contracts::factory::entry::QueryMsg as FactoryQueryMsg;
• pub use crate::contracts::market::entry::ExecuteMsg as MarketExecuteMsg;
• pub use crate::contracts::market::entry::QueryMsg as MarketQueryMsg;

Modules

• namespace
  This is a centralized location for cw_storage Item storage keys and Map namespaces
• ratio
  Provides specialized types that define a ratio that must be within a specific range. This can be helpful when defining an interface that contains a ratio represented by a decimal but the ratio is logically constrained by specific bounds.

Macros

• anyhow
  Construct an ad-hoc error from a string or existing non-anyhow error value.
• attr_map
  Makes it easy to create a Response where all the values are attributes, like a HashMap.
• bail
  Return early with an error.
• debug_log
  This version only logs if the given flag is in DEBUG_LOG_FLAGS (will not log if log_print feature is disabled, in that case it’s a no-op)
• debug_log_any
  This version will always log (except if log_print feature is not enabled, it’s a no-op)
• perp_anyhow
  Generate a PerpError and then wrap it up in an anyhow error
• perp_anyhow_data
  Like perp_anyhow but accepts optional extra data
• perp_bail
  Return early with the given perp error
• perp_bail_data
  Like perp_bail but takes extra optional data
• perp_ensure
  Ensure a condition is true, otherwise returns from the function with an error.
• perp_error
  Generate a PerpError value
• perp_error_data
  Generate a PerpError value with additional optional data

Structs

• Addr
  A human readable address.
• Base
  Unsigned value
• Collateral
  Unsigned value
• Decimal256
  A fixed-point decimal value with 18 fractional digits, i.e. Decimal256(1_000_000_000_000_000_000) == 1.0
• Duration
  A duration of time measured in nanoseconds
• Event
  A full Cosmos SDK event.
• FarmingToken
  Unsigned value
• Item
  Item stores one typed item at the given key. This is an analog of Singleton. It functions the same way as Path does but doesn’t use a Vec and thus has a const fn constructor.
• LeverageToBase
  The absolute leverage for a position, in terms of the base asset.
• LockdropShares
  Unsigned value
• LpToken
  Unsigned value
• LvnToken
  Unsigned value
• Map
• MarketId
  An identifier for a market.
• NonZero
  Ensure that the inner value is never 0.
• Notional
  Unsigned value
• PerpError
  An error message for the perps protocol
• Price
  The price of the pair as used internally by the protocol, given as collateral / notional.
• PriceBaseInQuote
  The price of the currency pair, given as quote / base, e.g. “20,000 USD per BTC”.
• PriceCollateralInUsd
  PriceBaseInQuote converted to USD
• PriceKey
  A modified version of a Price used as a key in a Map.
• PricePoint
  All prices in the protocol for a given point in time.
• Quote
  Unsigned value
• RawAddr
  A raw address passed in via JSON.
• ResponseBuilder
  Helper data type, following builder pattern, for constructing a [Response].
• Signed
  Wrap up any UnsignedDecimal to provide negative values too.
• SignedLeverageToBase
  The user-specified leverage for a position, with direction expressed as the signed value
• SignedLeverageToNotional
  Leverage calculated based on the protocol’s internal representation.
• Timestamp
  Essentially a newtype wrapper for Timestamp providing additional impls.
• Uint64
  A thin wrapper around u64 that is using strings for JSON encoding/decoding, such that the full u64 range can be used for clients that convert JSON numbers to floats, like JavaScript and jq.
• Usd
  Unsigned value

Enums

• AuthCheck
  Check that an addr satisfies auth checks
• Bound
  Bound is used to define the two ends of a range. None means that we don’t limit that side of the range at all. Inclusive means we use the given value as a limit and include anything at that exact key. Exclusive means we use the given value as a limit and exclude anything at that exact key.
• CongestionReason
  What was the user doing when they hit the congestion error message?
• DebugLog
  Flags for gating debug_log
• DirectionToBase
  Direction in terms of base
• DirectionToNotional
  Direction in terms of notional
• ErrorDomain
  Source within the protocol for the error
• ErrorId
  Unique identifier for an error within perps
• MarketError
  An error type for known market errors with potentially special error handling.
• MarketType
  Whether the collateral asset is the same as the quote or base asset.
• MaxGainsInQuote
  The max gains for a position.
• Order
• OrderInMessage
  Like cosmwasm_std::Order but serialized as a string and with a schema export
• TakeProfitTrader
  The take profit price for a position, as supplied by client messsages (in terms of BaseInQuote).
• TriggerPriceMustBe
  Was the price provided by the trader too high or too low?
• TriggerType
  What type of price trigger occurred?

Constants

• QUERY_MAX_LIMIT
  useful for placing an upper cap on query iterators as a safety measure to prevent exhausting resources on nodes that allow unbounded query gas

Traits

• Api
  Api are callbacks to system functions implemented outside of the wasm modules. Currently it just supports address conversion but we could add eg. crypto functions here.
• Context
  Provides the context method for Result.
• CosmwasmEventExt
  Extension trait to add methods to native cosmwasm events
• Display
  Format trait for an empty format, {}.
• FromStr
  Parse a value from a string
• QueryResultExt
  Makes it easy to call .query_result() on any Serialize and standardizes so query() entry points also return a ContractResult
• Storage
  Storage provides read and write access to a persistent storage. If you only want to provide read access, provide &Storage
• UnsignedDecimal
  Generalizes any newtype wrapper around a Decimal256.

Functions

• assert_auth
  Ensure that the given address passes the specified AuthCheck.
• external_map_has
  Check if a cw_storage_plus::Map in an external contract has a specific key
• extract_instantiated_addr
  Extract contract address from an instantiation event
• get_contract_version
  get_contract_version can be use in migrate to read the previous version of this contract
• load_external_item
  Load an cw_storage_plus::Item stored in an external contract
• load_external_map
  Load a value from a cw_storage_plus::Map stored in an external contract
• smart_query_no_parse
  Make a smart query, but do not parse the binary results as JSON.

Type Aliases

• Number
  A signed number type with high fidelity.
• NumberGtZero
  A special case of NonZero which stores a big endian array of data.
• Result
  Result<T, Error>

Attribute Macros

• cw_serde
