Struct holochain_core_types::time::Period

pub struct Period(_);

A human-readable time Period, implemented as a std::time::Duration (which is unsigned). Conversion to/from and Serializable to/from readable form: "1w2d3h4.567s", at full Duration precision; values > 1s w/ ms precision are formatted to fractional seconds w/ full precision, while values < 1s are formatted to integer ms, us or ns as appropriate. Accepts y/yr/year, w/wk/week, d/dy/day, h/hr/hour, m/min/minute, s/sec/second, ms/millis/millisecond, u/μ/micros/microsecond, n/nanos/nanosecond, singular or plural. The humantime and parse_duration crates are complex, incompatible with each other, depend on crates and/or do not compile to WASM.

Trait Implementations

impl Clone for Period

fn clone(&self) -> Period

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Period

Outputs the human-readable form of the Period's Duration, eg. "1y2w3d4h56m7.89s", "456ms". Debug output of Period specifier instead of underlying Duration seconds.

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<'d> Deserialize<'d> for Period

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error> where
    D: Deserializer<'d>, 

Deserialize this value from the given Serde deserializer.

impl Display for Period

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Eq for Period

impl<'_> From<&'_ Duration> for Period

fn from(d: &Duration) -> Self

Performs the conversion.

impl<'_> From<&'_ Period> for Duration

fn from(p: &Period) -> Self

Performs the conversion.

impl<'a> From<&'a Period> for JsonString

fn from(v: &Period) -> JsonString

Performs the conversion.

impl From<Duration> for Period

fn from(d: Duration) -> Self

Performs the conversion.

impl From<Period> for JsonString

fn from(v: Period) -> JsonString

Performs the conversion.

impl From<Period> for Timeout

fn from(p: Period) -> Self

Performs the conversion.

impl From<Period> for Duration

fn from(p: Period) -> Self

Performs the conversion.

impl FromStr for Period

type Err = HolochainError

The associated error which can be returned from parsing.

fn from_str(period_str: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Period

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl PartialEq<Period> for Period

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

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

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

This method tests for !=.

impl Serialize for Period

Serialization w/ serde_json to/from String. This means that a timestamp will be deserialized to an Period specification and validated, which may fail, returning a serde::de::Error. Upon serialization, the canonicalized Period specification will be used.

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error> where
    S: Serializer, 

Serialize this value into the given Serde serializer.

impl<'a> TryFrom<&'a JsonString> for Period

type Error = JsonError

The type returned in the event of a conversion error.

fn try_from(json_string: &JsonString) -> Result<Self, Self::Error>

impl TryFrom<JsonString> for Period

type Error = JsonError

The type returned in the event of a conversion error.

fn try_from(json_string: JsonString) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<String> for Period

type Error = HolochainError

The type returned in the event of a conversion error.

fn try_from(s: String) -> Result<Self, Self::Error>

Performs the conversion.
