Struct TryReserveError 

pub struct TryReserveError { /* private fields */ }

The error type for try_reserve methods.

This error is returned when memory allocation fails or when the capacity exceeds collection-specific limits.

Implementations

impl TryReserveError

pub fn kind(&self) -> TryReserveErrorKind

Returns the kind of allocation error that occurred.

Trait Implementations

impl Clone for TryReserveError

fn clone(&self) -> TryReserveError

Returns a duplicate 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 Display for TryReserveError

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

Formats the error message for display.

Provides information about why the allocation failed.

impl Error for TryReserveError

Implements the standard error trait for TryReserveError.

This enables using this error type with standard error handling mechanisms.

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 From<LayoutError> for TryReserveError

fn from(_: LayoutError) -> Self

Always evaluates to a TryReserveError with 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 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.
