pub struct Expr {
    pub id: NodeId,
    pub kind: ExprKind,
    pub span: Span,
    pub attrs: AttrVec,
}

Fields

id: NodeId

kind: ExprKind

span: Span

attrs: AttrVec

Methods

impl Expr

pub fn returns(&self) -> bool

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>

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

Attempts to reparse as Ty (for diagnostic purposes).

pub fn precedence(&self) -> ExprPrecedence
