Struct StdSystemTime

源代码

pub struct StdSystemTime;

展开描述

TimeSource 的默认实现

通过调用 SystemTime::now() 来实现 now。

trait 实现§

源代码 §

impl TimeSource for StdSystemTime

源代码 §

fn now(&self) -> SystemTime

获取 SystemTime::now() 或其模拟等价物

自动 trait 实现§

§

impl UnwindSafe for StdSystemTime

blanket 实现§

源代码 §

impl<T> Any for T
where T: 'static + ?Sized,

源代码 §

fn type_id(&self) -> TypeId

Gets the TypeId of self. 更多信息

源代码 §

impl<T> Borrow<T> for T
where T: ?Sized,

源代码 §

fn borrow(&self) -> &T

Immutably borrows from an owned value. 更多信息

源代码 §

impl<T> BorrowMut<T> for T
where T: ?Sized,

源代码 §

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. 更多信息

源代码 §

impl<T> From<T> for T

源代码 §

fn from(t: T) -> T

原样返回该参数。

源代码 §

impl<T> Instrument for T

源代码 §

fn instrument(self, span: Span) -> Instrumented<Self>

Instruments this type with the provided Span, returning an Instrumented wrapper. 更多信息

源代码 §

fn in_current_span(self) -> Instrumented<Self>

Instruments this type with the current Span, returning an Instrumented wrapper. 更多信息

源代码 §

impl<T, U> Into for T
where U: From<T>,

源代码 §

fn into(self) -> U

调用 U::from(self)。

也就是说，此转换行为完全由 From<T> for U 的实现决定。

源代码 §

impl<T, U> TryFrom for T
where U: Into<T>,

源代码 §

type Error = Infallible

The type returned in the event of a conversion error.

源代码 §

fn try_from(value: U) -> Result<T, <T as TryFrom>::Error>

执行转换。

源代码 §

impl<T, U> TryInto for T
where U: TryFrom<T>,

源代码 §

type Error = >::Error

The type returned in the event of a conversion error.

源代码 §

fn try_into(self) -> Result<U, >::Error>

执行转换。

源代码 §

impl<V, T> VZip<V> for T
where V: MultiLane<T>,

源代码 §

fn vzip(self) -> V

源代码 §

impl<T> WithSubscriber for T

源代码 §

fn with_subscriber<S>(self, subscriber: S) -> WithDispatch<Self>
where S: Into<Dispatch>,

Attaches the provided Subscriber to this type, returning a WithDispatch wrapper. 更多信息

源代码 §

fn with_current_subscriber(self) -> WithDispatch<Self>

Attaches the current default Subscriber to this type, returning a WithDispatch wrapper. 更多信息

源代码 §
