pub enum ReservationError {
    CapacityOverflow,
    AllocError {
        layout: Layout,
    },
}

An error returned when capacity reservation fails.

Variants

CapacityOverflow

Collection capacity overflow.

Is returned when a collection’s length-type L cannot represent the resulting overall capacity.

AllocError

Allocation error.

Is returned when the underlying memory allocator fails to fulfill an allocation request.

See alloc for more information.

Fields

layout: Layout

The layout passed to the underlying allocator.

Trait Implementations

impl Clone for ReservationError

fn clone(&self) -> ReservationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReservationError

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

Formats the value using the given formatter.

impl Display for ReservationError

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

Formats the value using the given formatter.

impl Error for ReservationError

Available on crate feature std only.

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

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

fn description(&self) -> &str

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

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 PartialEq for ReservationError

fn eq(&self, other: &ReservationError) -> 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.
