Struct TemplateCollector 

pub struct TemplateCollector { /* private fields */ }

Thread-safe encode-side sink for the schema templates a v2 build produces.

The encoder records each layer’s stripped schema prefix and embeds the returned hash in the frame; PackWriter::finalize snapshots the collector into the manifest’s schemas table. Content-addressed keys make the result independent of encode parallelism/order (design ★F1/E1): two tiles sharing a schema record the same entry, and the snapshot is sorted by hash.

Implementations

impl TemplateCollector

pub fn new() -> Self

New, empty collector.

pub fn record(&self, template: &[u8]) -> [u8; 16]

Record a template’s bytes (idempotent), returning its blake3-128 hash — the 16-byte reference the v2 frame carries.

pub fn snapshot(&self) -> Vec<([u8; 16], Vec<u8>)>

Snapshot of every recorded (hash, template bytes), sorted by hash (deduped by construction) — the byte-reproducible manifest order.

pub fn len(&self) -> usize

Number of distinct templates recorded so far.

pub fn is_empty(&self) -> bool

Whether no template has been recorded.

Trait Implementations

impl Debug for TemplateCollector

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

Formats the value using the given formatter.

impl Default for TemplateCollector

fn default() -> TemplateCollector

Returns the “default value” for a type.
