Struct Metapipeline 

pub struct Metapipeline {
    pub stages: Vec<Stage>,
    pub edges: Vec<(usize, usize)>,
}

A metapipeline: stages in issue order, with the producer→consumer buffer edges between them.

Fields

stages: Vec<Stage>

edges: Vec<(usize, usize)>

(writer_stage, reader_stage) pairs, writer < reader.

Implementations

impl Metapipeline

pub fn ii(&self) -> usize

The pipeline’s II: its slowest stage.

pub fn throughput(&self) -> f64

Iterations per cycle at steady state.

pub fn buffer_depth(writer: usize, reader: usize) -> usize

Spatial’s N-buffer rule: a memory written in stage writer and read in stage reader needs reader - writer + 1 buffers (adjacent stages: 2, i.e. double-buffering).

pub fn buffer_depths(&self) -> Vec<(usize, usize, usize)>

(writer, reader, depth) for every edge.

pub fn cycles(&self, iters: usize) -> usize

Cycles to run iters iterations end to end: fill (sum of stage latencies) + (iters - 1) * II.

pub fn fits(&self, target: &FabricTarget) -> Result<(), Unplaceable>

Gate the pipeline’s depth against a target’s Metapipeline capability — a typed refusal.

Trait Implementations

impl Clone for Metapipeline

fn clone(&self) -> Metapipeline

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Metapipeline

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

Formats the value using the given formatter.

impl PartialEq for Metapipeline

fn eq(&self, other: &Metapipeline) -> 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.

impl Serialize for Metapipeline

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
