Struct All

pub struct All { /* private fields */ }

Expand description

A Pattern that consumes a list of other patterns and only matches if all the child patterns do.

It will match the length of the longest pattern.

Implementations§

impl All

pub fn new(children: Vec<Box<dyn Pattern>>) -> Self

pub fn add(&mut self, p: Box<dyn Pattern>)
