Enum ArenaError 

pub enum ArenaError {
    InvalidConfiguration,
    EmptyAllocation,
    SizeOverflow,
    OutOfMemory {
        requested_bytes: u64,
    },
    StaleAllocation,
    EmptyGrowth,
    PageCountOverflow,
}

Invalid requests and stale allocation handles.

Variants

InvalidConfiguration

Page size and page count must both be non-zero.

EmptyAllocation

Zero-byte allocations are not meaningful.

SizeOverflow

The requested byte count cannot be represented by this arena.

OutOfMemory

No contiguous free run can satisfy the request.

Fields

requested_bytes: u64

Payload size that could not be placed.

StaleAllocation

The handle was already freed or belongs to an older allocation.

EmptyGrowth

A fixed-capacity arena cannot be extended by zero pages.

PageCountOverflow

The enlarged page count cannot be represented by the arena.

impl Eq for ArenaError

impl Error for ArenaError

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.

impl PartialEq for ArenaError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
