Struct AllocFailed 

pub struct AllocFailed {
    pub requested_size: usize,
    pub error_code: Option<i32>,
    pub kind: AllocErrorKind,
}

Error type for system memory allocation failures.

Fields

requested_size: usize

The size that was requested.

error_code: Option<i32>

Platform-specific error code, if available.

kind: AllocErrorKind

Error kind for better diagnostics.

Implementations

impl AllocFailed

pub fn new(size: usize) -> Self

pub fn with_code(size: usize, code: i32) -> Self

pub fn with_kind(size: usize, kind: AllocErrorKind) -> Self

pub fn out_of_memory(size: usize) -> Self

pub fn huge_pages_unavailable(size: usize) -> Self

pub fn mlock_failed(size: usize) -> Self

Trait Implementations

impl Clone for AllocFailed

fn clone(&self) -> AllocFailed

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AllocFailed

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

Formats the value using the given formatter.

impl Display for AllocFailed

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

Formats the value using the given formatter.

impl Error for AllocFailed

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.
