Expand description

Blanket extension trait for contexts that can compute layouts of types.

## Provided Methods§

source

#### fn layout_of(&self, ty: Ty<'tcx>) -> Self::LayoutOfResult

Computes the layout of a type. Note that this implicitly executes in “reveal all” mode, and will normalize the input type.

source

#### fn spanned_layout_of(&self, ty: Ty<'tcx>, span: Span) -> Self::LayoutOfResult

Computes the layout of a type, at `span`. Note that this implicitly executes in “reveal all” mode, and will normalize the input type.

## Implementors§
