Enum naga::back::spv::block::BlockExitDisposition

enum BlockExitDisposition {
    Used,
    Discarded,
}

What code generation did with a provided BlockExit value.

A function that accepts a BlockExit argument should return a value of this type, to indicate whether the code it generated ended up using the provided exit, or ignored it and did a non-local exit of some other kind (say, Break or Continue). Some callers must use this information to decide whether to generate the target block at all.

Variants

Used

The generated code used the provided BlockExit value. If it included a block label, the caller should be sure to actually emit the block it refers to.

Discarded

The generated code did not use the provided BlockExit value. If it included a block label, the caller should not bother to actually emit the block it refers to, unless it knows the block is needed for something else.
