Trait Implementations

impl ArchiveTypePlugin for NativeRustToolchainPlugin

Available on crate feature znippy-handler only.

fn name(&self) -> &str

Human-readable name

fn type_id(&self) -> i8

DenseUnion type_id this plugin writes to

fn meta(&self) -> HandlerMeta

Discovery metadata — name, aliases, type_id, claimed extensions and the per-handler subcommand “API”. Used by the registry to list and select handlers at runtime. The default derives a minimal record from Self::name / Self::type_id; native handlers override it with a richer record (aliases, ecosystem, extensions, commands).

fn run_command(&self, cmd: &str, args: &[String]) -> Result<()>

Dispatch a handler-specific subcommand (one of HandlerMeta::commands). Default: the handler exposes no extra subcommands.

fn matches_path(&self, path: &str) -> bool

Return true if this plugin wants to handle this file (checked before reading data). Default false means the plugin is never called for that path.

fn schema_fields(&self) -> Vec<Field>

The Arrow columns this module contributes to the index. The writer composes the on-disk schema as base columns + pkg_type + these fields. Each Field’s name must match the key the plugin uses in ExtensionRow::fields. Default: no columns.

fn extract_metadata(&self, path: &str, data: &[u8]) -> Option<ExtensionRow>

Per-file extraction. Return None to skip.

fn supports_batch(&self) -> bool

Whether this plugin benefits from batched processing.

fn batch_threshold(&self) -> usize

Byte threshold to trigger batch flush (default 200MB).

fn extract_batch(&self, items: &[BatchItem<'_>]) -> Vec<Option<ExtensionRow>>

Batch extraction — process many files at once (zero-copy borrows). Returns one Option per input item, in same order.

impl Default for NativeRustToolchainPlugin

Available on crate feature znippy-handler only.

fn default() -> Self

Returns the “default value” for a type.
