Struct SpirVInstruction 

pub struct SpirVInstruction {
    pub result_id: Option<u32>,
    pub result_type_id: Option<u32>,
    pub opcode: SpirVOp,
    pub operands: Vec<u32>,
}

A single SPIR-V instruction.

Every instruction has an opcode, optional result ID, and a list of word operands. The result type ID is stored as the first operand when the instruction produces a value.

Fields

result_id: Option<u32>

Result ID assigned to this instruction (None for side-effecting ops)

result_type_id: Option<u32>

Result type ID (present iff result_id is Some)

opcode: SpirVOp

The SPIR-V opcode

operands: Vec<u32>

Additional word operands (IDs, literals, enumerants)

Implementations

impl SpirVInstruction

pub fn with_result( result_id: u32, result_type_id: u32, opcode: SpirVOp, operands: Vec<u32>, ) -> Self

Create an instruction that produces a result value.

pub fn no_result(opcode: SpirVOp, operands: Vec<u32>) -> Self

Create an instruction without a result (e.g., OpStore, OpReturn).

pub fn emit_text(&self) -> String

Emit the instruction as a SPIR-V assembly text line.

pub fn word_count(&self) -> u32

Estimate the word count of this instruction.

Trait Implementations

impl Clone for SpirVInstruction

fn clone(&self) -> SpirVInstruction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SpirVInstruction

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

Formats the value using the given formatter.

impl PartialEq for SpirVInstruction

fn eq(&self, other: &SpirVInstruction) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
