Enum ArenaError 

pub enum ArenaError {
    SizeMismatch {
        expected: usize,
        got: usize,
    },
    RegionNotFound(usize),
}

Errors that can occur during arena operations.

Variants

SizeMismatch

The number of bytes provided does not match the slice’s expected size.

Fields

expected: usize

got: usize

RegionNotFound(usize)

The region index stored in an ArenaSlice does not exist.

Trait Implementations

impl Debug for ArenaError

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

Formats the value using the given formatter.

impl Display for ArenaError

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

Formats the value using the given formatter.

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: &ArenaError) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
