Struct Op 

pub struct Op {
    pub sym: Sym,
    pub ins: Vec<String>,
    pub access: Vec<Access>,
    pub out: String,
    pub dst: Dst,
    pub keeps: Vec<String>,
    pub covers: Vec<usize>,
}

One op of the graph: its symbol, its operands and how it reads each, its result and where that lands, the further results it writes whole, and the lifted ops it computes.

Fields

sym: Sym

ins: Vec<String>

access: Vec<Access>

out: String

dst: Dst

keeps: Vec<String>

covers: Vec<usize>

Implementations

impl Op

pub fn prim(&self) -> Option<&TensorOpSpec>

The primitive a lifted op is.

pub fn kind(&self) -> &str

The op’s kind: a primitive’s, a fused symbol’s class, View or Quantize.

pub fn result(&self) -> Option<&str>

The tensor the op computes whole into a buffer of its own: not one it lands rows or units of another in, nor one it updates in place (a row written into a table, an activation’s quantized form).

pub fn state_inputs(&self) -> Vec<usize>

The positions in ins of the operands the op writes in place: a primitive’s state, or any part’s.

pub fn writes(&self) -> Vec<&str>

Every tensor the op writes: its destination’s buffer, what it writes in place, what it keeps, and — for a fused op — every table or wider tensor a part lands its result in.

pub fn row_params(&self) -> Vec<&str>

The parameters that name the rows the op’s result, or any part’s, lands in.

Trait Implementations

impl Clone for Op

fn clone(&self) -> Op

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Op

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

Formats the value using the given formatter.
