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(Layout)

The allocator ran out of scratch space.

NotPoppedInReverseOrder

Fields

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

Scratch space was not popped in reverse order.

UnownedAllocation

The given allocation did not belong to the scratch allocator.

Trait Implementations

impl Debug for FixedSizeScratchError

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

Formats the value using the given formatter.

impl Display for FixedSizeScratchError

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

Formats the value using the given formatter.

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
