Function spirv_tools_sys::val::validator_options_set_scalar_block_layout

pub unsafe extern "C" fn validator_options_set_scalar_block_layout(
    opts: *mut ValidatorOptions,
    toggle: bool
)

Records whether the validator should use “scalar” block layout rules. Scalar layout rules are more permissive than relaxed block layout.

See Vulkan extnesion VK_EXT_scalar_block_layout. The scalar alignment is defined as follows:

• scalar alignment of a scalar is the scalar size
• scalar alignment of a vector is the scalar alignment of its component
• scalar alignment of a matrix is the scalar alignment of its component
• scalar alignment of an array is the scalar alignment of its element
• scalar alignment of a struct is the max scalar alignment among its members

For a struct in Uniform, StorageClass, or PushConstant:

• a member Offset must be a multiple of the member’s scalar alignment
• ArrayStride or MatrixStride must be a multiple of the array or matrix scalar alignment
