Enum NotationPart 

pub enum NotationPart {
    Literal(String),
    Placeholder(String),
    Prec(u32),
}

A single part of a notation pattern.

Notation patterns are sequences of literals and placeholders:

notation:50 lhs " + " rhs => HAdd.hAdd lhs rhs
             ^^^  ^^^^^  ^^^
         Placeholder Literal Placeholder

Variants

Literal(String)

A literal string token (e.g. " + ", "if")

Placeholder(String)

A placeholder for a variable position (e.g. lhs, rhs)

Prec(u32)

A precedence annotation on a placeholder

Trait Implementations

impl Clone for NotationPart

fn clone(&self) -> NotationPart

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NotationPart

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

Formats the value using the given formatter.

impl Display for NotationPart

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

Formats the value using the given formatter.

impl PartialEq for NotationPart

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