Struct AllocError

pub struct AllocError(/* private fields */);

The error type for allocation failure.

Implementations

impl AllocError

pub const fn new(layout: Layout) -> AllocError

Creates a new AllocError.

If the size of layout is zero, it means we do not know what the size is.

pub const fn layout(self) -> Layout

Returns the memory layout of the AllocError.

Trait Implementations

impl Clone for AllocError

fn clone(&self) -> AllocError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AllocError

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

Formats the value using the given formatter.

impl Display for AllocError

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

Formats the value using the given formatter.

impl Error for AllocError

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<TryReserveError> for AllocError

fn from(e: TryReserveError) -> AllocError

Converts to this type from the input type.
