Enum Segment

Source

pub enum Segment {
    Fused {
        instructions: Vec<ExecInstruction>,
        input_slots: Vec<usize>,
        output_slots: Vec<usize>,
        last_use: Vec<bool>,
    },
    Ffi(ExecInstruction),
    Host(ExecInstruction),
}

Expand description

A compiled execution segment.

Fused segments group consecutive non-host, non-FFI instructions that can share one backend execution session. FFI and host segments remain single-instruction boundaries in Phase 4.

§Examples

use tenferro::segment::{segment_exec_program, Segment};
use tenferro::exec::{ExecInstruction, ExecOp, ExecProgram};
use tenferro::DType;

let program = ExecProgram {
    instructions: vec![
        ExecInstruction {
            op: ExecOp::Add,
            input_slots: vec![0, 1],
            output_slots: vec![2],
            dtype: DType::F64,
            output_shapes: vec![vec![]],
            last_use: vec![false, true],
        },
        ExecInstruction {
            op: ExecOp::Negate,
            input_slots: vec![2],
            output_slots: vec![3],
            dtype: DType::F64,
            output_shapes: vec![vec![]],
            last_use: vec![true],
        },
    ],
    input_slots: vec![0, 1],
    output_slots: vec![3],
    n_slots: 4,
};

let segments = segment_exec_program(&program);
assert!(matches!(&segments[0], Segment::Fused { instructions, .. } if instructions.len() == 2));
