Enum DagError 

pub enum DagError {
    ArenaFull,
    DanglingId,
    NullSentinel,
    ArityOverflow,
}

DAG arena / dedup / interning failures.

Variants

ArenaFull

Trait Implementations

impl Clone for DagError

fn clone(&self) -> DagError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DagError

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

Formats the value using the given formatter.

impl Display for DagError

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

Formats the value using the given formatter.

impl PartialEq for DagError

fn eq(&self, other: &DagError) -> 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.
