Enum DefineMeasure 

pub enum DefineMeasure {
    Lex(Vec<usize>),
}

Optional measure attached to a (define …) declaration.

Variants

Lex(Vec<usize>)

Lexicographic measure: the listed argument indices (0-based) must strictly decrease in the standard left-to-right lexicographic order on every recursive call.

Trait Implementations

impl Clone for DefineMeasure

fn clone(&self) -> DefineMeasure

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DefineMeasure

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

Formats the value using the given formatter.

impl PartialEq for DefineMeasure

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