Enum SlabError 

pub enum SlabError {
    SlabIndexOutOfRange(usize, usize),
    SlotIndexOutOfRange(usize, usize, usize),
    SlotAlreadyFree {
        slab: usize,
        slot: usize,
    },
}

Errors returned by SlabAllocator.

Variants

SlabIndexOutOfRange(usize, usize)

A handle points outside the slab array bounds.

SlotIndexOutOfRange(usize, usize, usize)

A slot index is outside the capacity of the addressed slab.

SlotAlreadyFree

The addressed slot is free and cannot be read.

Fields

slab: usize

Slab index.

slot: usize

Slot index within the slab.

Trait Implementations

impl Debug for SlabError

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

Formats the value using the given formatter.

impl Display for SlabError

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

Formats the value using the given formatter.

impl Error for SlabError

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.
