Enum tracery::Node

pub enum Node {
    Tag(Tag),
    Text(String),
}

Represents a part of a single expandable string

This is used to represent both the plain text, and the expandable text sections of a string.

Example

let nodes = vec![
    Node::Tag(Tag::new("one")),
    Node::Text(" is the loneliest number".to_string()),
];
let rule = Rule::new(nodes);

assert_eq!(Rule::parse("#one# is the loneliest number")?, rule);

Variants

Tag(Tag)

A tag (a key surrounded by '#'s)

Text(String)

Plain text
