Enum TryReserveErrorKind 

pub enum TryReserveErrorKind {
    CapacityOverflow,
    AllocError {
        layout: Layout,
        non_exhaustive: (),
    },
}

Details of the allocation that caused a TryReserveError.

Variants

CapacityOverflow

Error due to the computed capacity exceeding the collection’s maximum (usually isize::MAX bytes).

AllocError

The memory allocator returned an error

Fields

layout: Layout

The layout of allocation request that failed

non_exhaustive: ()

Reserved field for future compatibility with the standard library. This aligns with an RFC for future allocator error handling: https://github.com/rust-lang/wg-allocators/issues/23

Trait Implementations

impl Clone for TryReserveErrorKind

fn clone(&self) -> TryReserveErrorKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TryReserveErrorKind

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

Formats the value using the given formatter.

impl From<LayoutError> for TryReserveErrorKind

fn from(_: LayoutError) -> Self

Always evaluates to TryReserveErrorKind::CapacityOverflow.

This conversion is used when a layout error occurs during allocation.

impl From<TryReserveErrorKind> for TryReserveError

fn from(kind: TryReserveErrorKind) -> Self

Creates a TryReserveError from a TryReserveErrorKind.

impl PartialEq for TryReserveErrorKind

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