Enum ArenaError 

pub enum ArenaError {
    OutOfMemory,
    InvalidIndex,
    TraceError,
}

Errors that can occur during arena operations.

Variants

OutOfMemory

Arena is full, cannot allocate more cells.

InvalidIndex

Invalid index (out of bounds or not allocated).

TraceError

An error occurred during garbage collection tracing. This can happen if the mark stack overflows or roots are invalid.

Implementations

impl ArenaError

pub const fn as_str(&self) -> &'static str

Get a human-readable description of the error.

pub const fn is_out_of_memory(&self) -> bool

Check if this error indicates the arena is full.

pub const fn is_invalid_index(&self) -> bool

Check if this error indicates an invalid index.

pub const fn is_trace_error(&self) -> bool

Check if this error is related to garbage collection.

Trait Implementations

impl Clone for ArenaError

fn clone(&self) -> ArenaError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ArenaError

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

Formats the value using the given formatter.

impl From<ArenaError> for EvalError

fn from(e: ArenaError) -> Self

Converts to this type from the input type.

impl From<ArenaError> for ParseError

fn from(e: ArenaError) -> ParseError

Converts to this type from the input type.

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.
