Implementations

impl AST

pub fn assign(pattern: Spanned<AST>, expression: Spanned<AST>) -> AST

Shortcut for creating an AST::Assign variant.

pub fn lambda(pattern: Spanned<AST>, expression: Spanned<AST>) -> AST

Shortcut for creating an AST::Lambda variant.

pub fn call(fun: Spanned<AST>, arg: Spanned<AST>) -> AST

Shortcut for creating an AST::Call variant.

fn clone(&self) -> AST

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AST

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