Variants

CapacityOverflow

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

new API

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

AllocError

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

new API

The memory allocator returned an error

Fields of AllocError

The layout of allocation request that failed

Trait Implementations

impl Clone for TryReserveError

pub 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

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

Formats the value using the given formatter.

impl Display for TryReserveError

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

Formats the value using the given formatter.

impl Error for TryReserveError

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

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

impl From<LayoutError> for TryReserveError

pub fn from(LayoutError) -> TryReserveError

Performs the conversion.

impl PartialEq<TryReserveError> for TryReserveError

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

This method tests for self and other values to be equal, and is used by ==.
