Struct LayoutConfig

pub struct LayoutConfig {
    pub ignore_legacy_align: bool,
    pub min_aggregate_legacy_align: u32,
    pub abstract_bool_size_align: (u32, u32),
    pub logical_ptr_size_align: (u32, u32),
}

Various toggles for layout-related behavior that is not unambiguous from the SPIR-V alone, or involves intermediary illegal SPIR-V (during legalization).

Fields

ignore_legacy_align: bool

min_aggregate_legacy_align: u32

abstract_bool_size_align: (u32, u32)

Assumed size and alignment for OpTypeBool, even if unusable with externally-visible concrete memory (i.e. buffers).

This is only useful for accurate handling of illegal SPIR-V relying on e.g. pointer casts, and as such defaults to (1, 1), to merely ensure unique offsets and guarantee qptr::lift can tell fields apart.

logical_ptr_size_align: (u32, u32)

Assumed size and alignment for logical OpTypePointers, even if unusable with externally-visible concrete memory (i.e. buffers).

This is only useful for accurate handling of illegal SPIR-V relying on e.g. pointer casts, and as such defaults to (1, 1), to merely ensure unique offsets and guarantee qptr::lift can tell fields apart.
