Enum AllocError

#[repr(u8)]
pub enum AllocError {
    ArithmeticOverflow,
    LayoutError(usize, usize),
    AllocFailed(Layout),
    GrowSmallerNewLayout(usize, usize),
    ShrinkBiggerNewLayout(usize, usize),
}

Errors for allocation operations.

Variants

ArithmeticOverflow

A basic arithmetic operation overflowed.

LayoutError(usize, usize)

The layout computed with the given size and alignment is invalid.

AllocFailed(Layout)

The underlying allocator failed to allocate using the given layout.

GrowSmallerNewLayout(usize, usize)

Attempted to grow to a smaller layout.

ShrinkBiggerNewLayout(usize, usize)

Attempted to shrink to a larger layout.

Trait Implementations

impl Debug for AllocError

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

Formats the value using the given formatter.

impl Display for AllocError

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

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 PartialEq for AllocError

fn eq(&self, other: &AllocError) -> 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.
