#[non_exhaustive]pub struct Event<T: ?Sized> {
pub at: SystemTime,
pub value: T,
}
Expand description
Arbitrary event, optionally paired with additional metadata.
Any metadata is added by enabling the correspondent library feature:
timestamps
: adds time of when thisEvent
has happened.
Fields (Non-exhaustive)§
This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional
Struct { .. }
syntax; cannot be matched against without a wildcard ..
; and struct update syntax will not work.at: SystemTime
Available on crate feature
timestamps
only.SystemTime
when this Event
has happened.
value: T
Actual value of this Event
.
Implementations§
source§impl<T> Event<T>
impl<T> Event<T>
sourcepub fn into_inner(self) -> T
pub fn into_inner(self) -> T
Unwraps the inner Event::value
loosing all the attached metadata.
sourcepub fn split(self) -> (T, Metadata)
pub fn split(self) -> (T, Metadata)
Splits this Event
to the inner Event::value
and its detached
metadata.
sourcepub fn insert<V>(self, value: V) -> Event<V>
pub fn insert<V>(self, value: V) -> Event<V>
Replaces the inner Event::value
with the given one, dropping the old
one in place.
sourcepub fn map<V>(self, f: impl FnOnce(T) -> V) -> Event<V>
pub fn map<V>(self, f: impl FnOnce(T) -> V) -> Event<V>
Maps the inner Event::value
with the given function.
sourcepub fn replace<V>(self, value: V) -> (T, Event<V>)
pub fn replace<V>(self, value: V) -> (T, Event<V>)
Replaces the inner Event::value
with the given one, returning the
old one along.
