Struct WordExprGroup

Source
pub struct WordExprGroup<E>
where E: Expr,
{ /* private fields */ }
Expand description

An expression collection to look for expressions that start with a specific word.

The benefit of using this struct over other methods increases for larger collections.

Implementations§

Source§

impl WordExprGroup<FirstMatchOf>

Source

pub fn add(&mut self, word: &str, expr: Box<dyn Expr>)

Source

pub fn add_word(&mut self, word: &'static str)
