Enum PatternToken 

pub enum PatternToken {
    Literal(Segment),
    One,
    Tail,
}

One token of a Pattern.

Variants

Literal(Segment)

A literal label — matches itself and nothing else.

One

* — matches exactly one segment, whatever it is.

Tail

> — matches one-or-more remaining segments. Only ever the final token; a > elsewhere is a parse error, so a Pattern with a mid-sequence Tail is unrepresentable.

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for PatternToken

fn partial_cmp(&self, other: &PatternToken) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.
