Struct Program 

pub struct Program { /* private fields */ }

A compiled dialogue program ready to be executed by the runner.

Implementations

impl Program

pub fn node_exists(&self, title: &str) -> bool

Returns true if the program contains a node with the given title.

Example

let prog = bubbles::compile("title: Start\n---\n===\n").unwrap();
assert!(prog.node_exists("Start"));
assert!(!prog.node_exists("Missing"));

pub fn node_titles(&self) -> impl Iterator<Item = &str>

Iterates over all node titles in insertion order.

pub fn node_tags(&self, title: &str) -> Option<&[String]>

Returns the tags of the first node with the given title, if any.

pub fn variable_declarations(&self) -> &[VariableDecl]

Returns all <<declare>> variable declarations found in the program.

This is useful for save systems that need to enumerate every variable a script declares, and for editor tooling.

Example

let prog = bubbles::compile(
    "title: Start\n---\n<<declare $health = 100>>\n===\n"
).unwrap();
let decls = prog.variable_declarations();
assert_eq!(decls.len(), 1);
assert_eq!(decls[0].name, "$health");
assert_eq!(decls[0].default_src, "100");

Trait Implementations

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Program

fn fmt(&self, f: &mut Formatter<'_>) -> Result
