Methods

impl Val

pub fn type_name(&self) -> String

Returns the Type of a Val as a string.

pub fn equal(&self, target: &Self, pos: Position) -> Result<bool, BuildError>

pub fn get_fields(&self) -> Option<&Vec<(PositionedItem<String>, Rc<Val>)>>

Returns the fields if this Val is a tuple. None otherwise.
