pub struct LayoutShape {

}
Expand description

The layout of a type in memory.

Fields§

§fields: FieldsShape

The fields location withing the layout

§variants: VariantsShape

Encodes information about multi-variant layouts. Even with Multiple variants, a layout still has its own fields! Those are then shared between all variants.

To access all fields of this layout, both fields and the fields of the active variant must be taken into account.

§abi: ValueAbi

The abi defines how this data is passed between functions.

§abi_align: Align

The ABI mandated alignment in bytes.

§size: MachineSize

The size of this layout in bytes.

Implementations§

source§

impl LayoutShape

source

pub fn is_unsized(&self) -> bool

Returns true if the layout corresponds to an unsized type.

source

pub fn is_sized(&self) -> bool

source

pub fn is_1zst(&self) -> bool

Returns true if the type is sized and a 1-ZST (meaning it has size 0 and alignment 1).

impl PartialEq for LayoutShape

source§

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
