Enum ConsumerKind 

pub enum ConsumerKind {
    StringJoin,
}

What the matched builder feeds into. Different consumers compile to different buffer types and finalizers, but all share the same underlying deforestation: skip the intermediate List, write elements straight to the consumer’s storage.

Phase 2 implements StringJoin only — the canonical case from the fractal demo. Future variants land as separate phases: VectorFromList (already half-fused via Vector.set owned-mutate in 0.14.0; deforestation closes the cons-cell side), and ListFold for stream-fusion-style consumer rewrites.

Variants

StringJoin

String.join(builder(...), sep) — write each element + sep directly into a Vec<u8>-shaped buffer in linear memory.

Trait Implementations

impl Clone for ConsumerKind

fn clone(&self) -> ConsumerKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConsumerKind

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

Formats the value using the given formatter.

impl PartialEq for ConsumerKind

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