Struct When 

pub struct When {
    pub time: EventTime,
}

Wrapper that answers when a lifecycle fact happened.

Fields

time: EventTime

Detailed timing data for the event.

Implementations

impl When

pub fn new(time: EventTime) -> Self

Creates a When value from event time.

Arguments

• time: Event time captured by the caller.

Returns

Returns a When wrapper.

Examples

let when = rust_supervisor::event::time::When::new(
    rust_supervisor::event::time::EventTime::deterministic(
        1,
        1,
        0,
        rust_supervisor::id::types::Generation::initial(),
        rust_supervisor::id::types::Attempt::first(),
    ),
);
assert_eq!(when.time.unix_nanos, 1);

Trait Implementations

impl Clone for When

fn clone(&self) -> When

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for When

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for When

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for When

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for When

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
