Enum DoneReason

pub enum DoneReason {
    DeadlineExceeded,
    Canceled,
}

The reason why a context was stopped, see Context.done. This “error” can be turned into an io::Error by using the Into trait (From<DoneReason> is implemented for io::Error).

Variants

DeadlineExceeded

The deadline was exceeded.

Canceled

The context was canceled.

Implementations

impl DoneReason

pub fn into_error<E>(self) -> E

where E: From<Error>,

Convert the DoneReason into an error.

Trait Implementations

impl Clone for DoneReason

fn clone(&self) -> DoneReason

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DoneReason

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

Formats the value using the given formatter.

impl Display for DoneReason

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

Formats the value using the given formatter.

impl Error for DoneReason

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl From<DoneReason> for Error

fn from(reason: DoneReason) -> Self

Converts to this type from the input type.

impl PartialEq for DoneReason

fn eq(&self, other: &DoneReason) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
