Enum AllocError

#[non_exhaustive]
pub enum AllocError {
    NoData,
    Leak,
    DoubleFree,
    BadPtr,
    BadSize,
    BadAlignment,
    BadLayout,
}

Types of allocation bug which can be detected by the allocator.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NoData

No allocations were detected. Perhaps Mockalloc isn’t enabled as the global allocator?

Leak

There were more calls to alloc than to dealloc.

DoubleFree

There were more calls to dealloc than to alloc.

BadPtr

A pointer was passed to dealloc which was not previously returned by alloc.

BadSize

The size specified in a call to dealloc did not match that specified in the corresponding alloc call.

BadAlignment

The alignment specified in a call to dealloc did not match that specified in the corresponding alloc call.

BadLayout

The size and alignment specified in a call to dealloc did not match those specified in the corresponding alloc call.

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

Formats the value using the given formatter.

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.
