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

impl Eq for TryReserveError

impl Error for TryReserveError

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 TryReserveError

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

Equality operator ==.

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

Inequality operator !=.
