Struct ErrorScopeGuard 

pub struct ErrorScopeGuard { /* private fields */ }

Available on crate feature wgpu only.

Guard for an error scope pushed with Device::push_error_scope().

Call pop() to pop the scope and get a future for the result. If the guard is dropped without being popped explicitly, the scope will still be popped, and the captured errors will be dropped.

This guard is neither Send nor Sync, as error scopes are handled on a per-thread basis when the std feature is enabled.

Implementations

impl ErrorScopeGuard

pub fn pop(self) -> impl Future<Output = Option<Error>> + WasmNotSend

Pops the error scope.

Returns a future which resolves to the error captured by this scope, if any. The pop takes effect immediately; the future does not need to be awaited before doing work that is outside of this error scope.

Trait Implementations

impl Debug for ErrorScopeGuard

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

Formats the value using the given formatter.

impl Drop for ErrorScopeGuard

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
