Trait Implementations

impl ArchiveTypePlugin for DatasetPlugin

fn spec(&self) -> &HandlerSpec

The handler’s static description.

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

Per-file extraction. Return None to skip.

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

Dispatch a subcommand. Default: the shared coords command.

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

Return true if this plugin wants to handle this file: the spec’s Claim. Override it only to make the same decision faster; the register’s tests hold every handler to spec().claims.

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

The Arrow columns this handler contributes. Default: the spec’s fields.

fn name(&self) -> &str

fn type_id(&self) -> i8

fn meta(&self) -> HandlerMeta

Owned discovery record, derived from the spec.
