Struct tracing::instrument::Instrumented[][src]

#[must_use = "futures do nothing unless you `.await` or poll them"]pub struct Instrumented<T> { /* fields omitted */ }

A future that has been instrumented with a tracing span.

Implementations

impl<T> Instrumented<T>[src]

pub fn span(&self) -> &Span[src]

Borrows the Span that this type is instrumented by.

pub fn span_mut(&mut self) -> &mut Span[src]

Mutably borrows the Span that this type is instrumented by.

pub fn inner(&self) -> &T[src]

Borrows the wrapped type.

pub fn inner_mut(&mut self) -> &mut T[src]

Mutably borrows the wrapped type.

pub fn inner_pin_ref(self: Pin<&Self>) -> Pin<&T>[src]

Get a pinned reference to the wrapped type.

pub fn inner_pin_mut(self: Pin<&mut Self>) -> Pin<&mut T>[src]

Get a pinned mutable reference to the wrapped type.

pub fn into_inner(self) -> T[src]

Consumes the Instrumented, returning the wrapped type.

Note that this drops the span.
