pub struct Builder {
    pub last: Option<Rc<Val>>,
    // some fields omitted
}

Builder handles building ucg code for a single file..

Fields

last: Option<Rc<Val>>

last is the result of the last statement.

Methods

impl Builder

pub fn new<P: Into<PathBuf>>(root: P, cache: Rc<RefCell<Cache>>) -> Self

Constructs a new Builder.

pub fn new_with_scope<P: Into<PathBuf>>(     root: P,     cache: Rc<RefCell<Cache>>,     scope: HashMap<Positioned<String>, Rc<Val>> ) -> Self

Constructs a new Builder with a provided scope.

pub fn new_with_env_and_scope<P: Into<PathBuf>>(     root: P,     cache: Rc<RefCell<Cache>>,     scope: HashMap<Positioned<String>, Rc<Val>>,     env: Rc<Val> ) -> Self

pub fn get_out_by_name(&self, name: &str) -> Option<Rc<Val>>

Returns a Val by name from previously built UCG.

pub fn enable_validate_mode(&mut self)

Puts the builder in validation mode.

Among other things this means that assertions will be evaluated and their results will be saved in a report for later output.

pub fn build(&mut self, ast: &Vec<Statement>) -> Result<(), Box<Error>>

Builds a list of parsed UCG Statements.

pub fn eval_string(&mut self, input: &str) -> Result<Rc<Val>, Box<Error>>

Evaluate an input string as UCG.

pub fn build_file(&mut self, name: &str) -> Result<(), Box<Error>>

Builds a ucg file at the named path.

pub fn eval_expr(&self, expr: &Expression) -> Result<Rc<Val>, Box<Error>>
