Struct FusionGroup 

pub struct FusionGroup {
    pub members: Vec<usize>,
    pub external_inputs: Vec<usize>,
    pub external_outputs: Vec<usize>,
    pub internal_intermediates: Vec<usize>,
    pub bytes_read: u64,
    pub bytes_written: u64,
}

A group of ops fused into a single kernel.

members is the set of op ids in the group (sorted ascending). external_inputs are the producer op ids outside the group that the group reads. external_outputs are member ids whose results must be materialized (consumed outside the group, or graph terminals). internal_intermediates are members whose results stay in registers and are elided.

Fields

members: Vec<usize>

Op ids fused into this kernel (sorted ascending).

external_inputs: Vec<usize>

Producer op ids outside the group that the group reads (sorted).

external_outputs: Vec<usize>

Member op ids whose outputs are written to memory (sorted).

internal_intermediates: Vec<usize>

Member op ids whose outputs are fully elided into registers (sorted).

bytes_read: u64

Bytes read by this group (external inputs, each counted once).

bytes_written: u64

Bytes written by this group (external outputs).

Implementations

impl FusionGroup

pub fn bytes_fused(&self) -> u64

Total fused bytes moved by this group (bytes_read + bytes_written).

pub fn is_fused(&self) -> bool

Returns true if the group fuses more than one op.

Trait Implementations

impl Clone for FusionGroup

fn clone(&self) -> FusionGroup

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FusionGroup

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

Formats the value using the given formatter.
