Modules§

workgroup_mem_init 🔒: Initializing workgroup variables is more tricky for Metal because we have to deal with atomics at the type-level (which don’t have a copy constructor).

ArraySizeMember 🔒: Wrapper for generating struct _mslBufferSizes member names for runtime-sized array lengths.
ClampedLod 🔒: Wrapper for identifier names for clamped level-of-detail values
ExpressionContext 🔒
Reinterpreted 🔒: Wrapper for reinterpreted variables using as_type<target_type>(orig).
StatementContext 🔒
TexelAddress 🔒: Values needed to select a particular texel for ImageLoad and ImageStore.

ABS_FUNCTION 🔒
ARGUMENT_BUFFER_WRAPPER_STRUCT 🔒: For some reason, Metal does not let you have metal::texture<..>* as a buffer argument. However, if you put that texture inside a struct, everything is totally fine. This baffles me to no end.
ATOMIC_COMP_EXCH_FUNCTION 🔒
ATOMIC_REFERENCE 🔒
CLAMPED_LOD_LOAD_PREFIX 🔒: Prefix for cached clamped level-of-detail values for ImageLoad expressions.
DIV_FUNCTION 🔒
EXTERNAL_TEXTURE_WRAPPER_STRUCT 🔒: Name of the struct that is declared to wrap the 3 textures and parameters buffer that crate::ImageClass::External variables are lowered to, allowing them to be conveniently passed to user-defined or wrapper functions. The struct is declared in Writer::write_type_defs.
