Struct ProgramDescriptor 

#[non_exhaustive]
pub struct ProgramDescriptor {
    pub buffer_count: usize,
    pub workgroup_size: [u32; 3],
    pub buffers: Vec<BufferDescriptor>,
    pub rw_bytes_lower_bound: usize,
    pub entry_node_count: usize,
}

Structural description of a Cat-A Program.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

buffer_count: usize

Number of declared buffers.

workgroup_size: [u32; 3]

Canonical workgroup dispatch size.

buffers: Vec<BufferDescriptor>

Buffer summaries, one per declared buffer.

rw_bytes_lower_bound: usize

Total element-bytes declared across ReadWrite buffers. Useful for rough memory-footprint estimates. Missing counts (runtime- determined buffer sizes) contribute zero.

entry_node_count: usize

Number of top-level nodes in the entry body.

Implementations

impl ProgramDescriptor

pub fn new( buffer_count: usize, workgroup_size: [u32; 3], buffers: Vec<BufferDescriptor>, rw_bytes_lower_bound: usize, entry_node_count: usize, ) -> Self

Construct a ProgramDescriptor directly from explicit fields. External tooling that synthesizes descriptors without going through from_program uses this constructor (V7-EXT-023).

pub fn from_program(program: &Program) -> Self

Derive a descriptor from an already-built Program. Zero-allocation aside from the owned buffer-name strings (one per declared buffer); consumers that need every dispatch to stay cheap should cache the descriptor once and reuse it.

Trait Implementations

impl Clone for ProgramDescriptor

fn clone(&self) -> ProgramDescriptor

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ProgramDescriptor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
