Methods

impl Expr[src]

pub fn returns(&self) -> bool[src]

Returns true if this expression would be valid somewhere that expects a value; for example, an if condition.

pub fn to_bound(&self) -> Option<GenericBound>[src]

pub fn to_ty(&self) -> Option<P<Ty>>[src]

Attempts to reparse as Ty (for diagnostic purposes).

pub fn precedence(&self) -> ExprPrecedence[src]
