Enum LevelConstraint 

pub enum LevelConstraint {
    Leq(Level, Level),
    Eq(Level, Level),
}

A level constraint: an assertion that l1 ≤ l2 or l1 = l2.

Variants

Leq(Level, Level)

l1 ≤ l2

Eq(Level, Level)

l1 = l2 (syntactic equality after normalization)

Implementations

impl LevelConstraint

pub fn is_satisfied(&self) -> bool

Check whether this constraint is satisfied.

Uses is_leq / is_equivalent from this module.

pub fn levels(&self) -> (&Level, &Level)

Return both levels involved in this constraint.

Trait Implementations

impl Clone for LevelConstraint

fn clone(&self) -> LevelConstraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LevelConstraint

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

Formats the value using the given formatter.

impl PartialEq for LevelConstraint

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