Struct Node 

pub struct Node {
    pub edges: BTreeMap<Edge, Node>,
    pub func: Option<Box<dyn Fn(&mut State, &mut dyn Write, &[&str]) -> Result<ControlFlow<()>>>>,
}

The available commands form a rooted tree where the tokens are represented by edges.

Fields

edges: BTreeMap<Edge, Node>

func: Option<Box<dyn Fn(&mut State, &mut dyn Write, &[&str]) -> Result<ControlFlow<()>>>>

Implementations

impl Node

pub fn root() -> Self

pub fn traverse(&self, args: &[&str]) -> Option<&Self>

pub fn next_keywords_by_prefix( &self, prefix: &str, ) -> impl Iterator<Item = &str>
