Enum rkyv::ser::serializers::FixedSizeScratchError

pub enum FixedSizeScratchError {
    OutOfScratch(Layout),
    NotPoppedInReverseOrder {

Errors that can occur when using a fixed-size allocator.

Pairing a fixed-size allocator with a fallback allocator can help prevent running out of scratch space unexpectedly.

Variants

OutOfScratch

The allocator ran out of scratch space.

Tuple Fields of OutOfScratch

0: Layout

NotPoppedInReverseOrder

Scratch space was not popped in reverse order.

Fields of NotPoppedInReverseOrder

pos: usize

The current position of the start of free memory

next_pos: usize

The next position according to the erroneous pop

next_size: usize

The size of the memory according to the erroneous pop

UnownedAllocation

The given allocation did not belong to the scratch allocator.

Trait Implementations

impl Error for FixedSizeScratchError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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
