Enum TryReserveError

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

The error type for try_reserve methods.

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 the allocation request that failed.

Trait Implementations

impl Clone for TryReserveError

fn clone(&self) -> TryReserveError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TryReserveError

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

Formats the value using the given formatter.

impl PartialEq for TryReserveError

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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
