Struct levana_perpswap_cosmos::time::Timestamp

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

Essentially a newtype wrapper for Timestamp providing additional impls.

Internal representation in nanoseconds since the epoch. We keep a u64 directly (instead of a Timestamp or cosmwasm_std::Uint64) to make it easier to derive some impls. The result is that we need to explicitly implement Serialize and Deserialize to keep the stringy representation.

Implementations

impl Timestamp

pub fn from_nanos(nanos: u64) -> Self

Construct a new value from the given number of nanoseconds since the epoch

pub fn from_seconds(seconds: u64) -> Self

Construct a new value from the given number of seconds since the epoch

pub fn from_millis(millis: u64) -> Self

Construct a new value from the given number of millisecond since the epoch.

pub fn plus_seconds(self, secs: u64) -> Self

Add the given number of seconds to the given timestamp

pub fn checked_sub(self, rhs: Self, desc: &str) -> Result<Duration>

Subtract two timestamps to get the duration between them.

Will fail if the right hand side is greater than the left hand side.

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(gen: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl KeyDeserialize for Timestamp

type Output = Timestamp

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 Ord for Timestamp

fn cmp(&self, other: &Timestamp) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Timestamp

fn eq(&self, other: &Timestamp) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Timestamp

fn partial_cmp(&self, other: &Timestamp) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

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

impl<'a> PrimaryKey<'a> for Timestamp

type Prefix = ()
