Struct levana_perpswap_cosmos::price::PriceKey

pub struct PriceKey(/* private fields */);

A modified version of a Price used as a key in a Map.

Due to how cw-storage-plus works, we need to have a reference to a slice, which we can’t get from a Decimal256. Instead, we store an array directly here and provide conversion functions.

Trait Implementations

impl Clone for PriceKey

fn clone(&self) -> PriceKey

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl From<Price> for PriceKey

fn from(price: Price) -> Self

Converts to this type from the input type.

impl KeyDeserialize for PriceKey

type Output = Price

const KEY_ELEMS: u16 = 1u16

The number of key elements is used for the deserialization of compound keys. It should be equal to PrimaryKey::key().len()

fn from_vec(value: Vec<u8>) -> StdResult<Self::Output>

fn from_slice(value: &[u8]) -> Result<Self::Output, StdError>

impl<'a> Prefixer<'a> for PriceKey

fn prefix(&self) -> Vec<Key<'_>>

returns 0 or more namespaces that should be length-prefixed and concatenated for range searches

fn joined_prefix(&self) -> Vec<u8>

impl<'a> PrimaryKey<'a> for PriceKey

type Prefix = ()

These associated types need to implement Prefixer, so that they can be useful arguments for prefix(), sub_prefix(), and their key-deserializable variants.

type SubPrefix = ()

type Suffix = PriceKey

These associated types need to implement KeyDeserialize, so that they can be returned from range_de() and friends.

type SuperSuffix = PriceKey

fn key(&self) -> Vec<Key<'_>>

returns a slice of key steps, which can be optionally combined

fn joined_key(&self) -> Vec<u8>

fn joined_extra_key(&self, key: &[u8]) -> Vec<u8>
