Struct rustc_hir::Expr[][src]

pub struct Expr<'hir> {
    pub hir_id: HirId,
    pub kind: ExprKind<'hir>,
    pub span: Span,
}
Expand description

An expression.

Fields

hir_id: HirIdkind: ExprKind<'hir>span: Span

Implementations

Whether this is a place expression.

allow_projections_from should return true if indexing a field or index expression based on the given expression should be considered a place expression.

If Self.kind is ExprKind::DropTemps(expr), drill down until we get a non-DropTemps Expr. This is used in suggestions to ignore this ExprKind as it is semantically silent, only signaling the ownership system. By doing this, suggestions that check the ExprKind of any given Expr for presentation don’t have to care about DropTemps beyond remembering to call this function before doing analysis on it.
