Enum ReallocFailure 

#[non_exhaustive]
pub enum ReallocFailure {
    InvalidLayout {
        new_size: usize,
        alignment: usize,
    },
    InvalidSourceLayout {
        requested_size: usize,
        alignment: usize,
        usable_size: usize,
    },
    AllocationFailed,
}

The reason a branded reallocation could not produce a replacement block.

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.

InvalidLayout

new_size and the existing alignment cannot form a valid Layout.

Fields

new_size: usize

The requested new size.

alignment: usize

The existing block alignment the new size had to satisfy.

InvalidSourceLayout

The supplied source layout exceeds the block’s usable capacity or requires an alignment the source pointer does not satisfy.

Fields

requested_size: usize

Size named by the caller-supplied source layout.

alignment: usize

Alignment named by that layout.

usable_size: usize

Capacity the block actually provides.

AllocationFailed

The requested replacement allocation could not be obtained.
