}

Types holds all the codegen Types for semantic types and the runtime. Types augments the codegen.Types structure.

func (*Types) AlignOf added in v1.2.0 

func (t *Types) AlignOf(layout *device.MemoryLayout, ty semantic.Type) uint64

AlignOf returns the alignment of this type in bytes for the given memory layout.

func (*Types) Capture added in v1.2.0 

func (t *Types) Capture(ty semantic.Type) codegen.Type

Capture returns the codegen type used to represent ty when stored in a capture's buffer.

func (*Types) SizeOf added in v1.2.0 

func (t *Types) SizeOf(layout *device.MemoryLayout, ty semantic.Type) uint64

SizeOf returns size of the type for the given memory layout.

func (*Types) StrideOf added in v1.2.0 

func (t *Types) StrideOf(layout *device.MemoryLayout, ty semantic.Type) uint64

StrideOf returns the number of bytes per element when held in an array for the given memory layout.

func (*Types) Target 

func (t *Types) Target(ty semantic.Type) codegen.Type

Target returns the codegen type used to represent ty in the target-preferred form.
