Struct Builder 

pub struct Builder { /* private fields */ }

Accumulates SPIR-V words per section and hands out result ids.

Implementations

impl Builder

pub fn new() -> Self

pub fn id(&mut self) -> u32

A fresh result <id>. Ids start at 1; 0 is never valid.

pub fn inst(&mut self, s: Section, op: u16, operands: &[u32])

Emit one instruction with no result id.

pub fn typed( &mut self, s: Section, op: u16, result_type: u32, rest: &[u32], ) -> u32

Emit one instruction whose operands are [result_type, result_id, ..rest] and return result_id.

pub fn result(&mut self, s: Section, op: u16, rest: &[u32]) -> u32

Emit one instruction whose only leading operand is its result id (OpTypeInt, OpLabel, …) and return that id.

pub fn inst_str( &mut self, s: Section, op: u16, head: &[u32], text: &str, tail: &[u32], )

Emit an instruction that carries a trailing SPIR-V literal string (OpName, OpEntryPoint).

pub fn finish(self) -> Vec<u32>

The finished module: header followed by every section in layout order.

Trait Implementations

impl Default for Builder

fn default() -> Builder

Returns the “default value” for a type.
