Expand description

Extension trait for Future to provide contextual information on Reports.

Required Methods§

Source

fn attach<A>(self, attachment: A) -> FutureWithAttachment<Self, A>
where A: Send + Sync + 'static,

Adds a new attachment to the Report inside the Result when polling the Future.

Applies Report::attach on the Err variant, refer to it for more information.

Source

fn attach_lazy<A, F>(self, attachment: F) -> FutureWithLazyAttachment<Self, F>
where A: Send + Sync + 'static, F: FnOnce() -> A,

Lazily adds a new attachment to the Report inside the Result when polling the Future.

Applies Report::attach on the Err variant, refer to it for more information.

Source

fn attach_printable<A>( self, attachment: A, ) -> FutureWithPrintableAttachment<Self, A>
where A: Display + Debug + Send + Sync + 'static,

Adds a new printable attachment to the Report inside the Result when polling the Future.

Applies Report::attach_printable on the Err variant, refer to it for more information.

Source

fn attach_printable_lazy<A, F>( self, attachment: F, ) -> FutureWithLazyPrintableAttachment<Self, F>
where A: Display + Debug + Send + Sync + 'static, F: FnOnce() -> A,

Lazily adds a new printable attachment to the Report inside the Result when polling the Future.

Applies Report::attach_printable on the Err variant, refer to it for more information.

Source

fn change_context<C>(self, context: C) -> FutureWithContext<Self, C>
where C: Context,

Changes the Context of the Report inside the Result when polling the Future.

Applies Report::change_context on the Err variant, refer to it for more information.

Source

fn change_context_lazy<C, F>(self, context: F) -> FutureWithLazyContext<Self, F>
where C: Context, F: FnOnce() -> C,

Lazily changes the Context of the Report inside the Result when polling the Future.

Applies Report::change_context on the Err variant, refer to it for more information.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
