Expand description

A source capable of fetching transcripts from a media platform.

Implementations are expected to be cheap to construct; per-request state (HTTP client, auth, etc.) lives inside the implementor.

The trait is Send + Sync so implementations can be used behind Box<dyn TranscriptSource> for runtime dispatch (e.g. once omni-dev transcript fetch <url> auto-detection lands in a follow-up).

Required Methods§

Source

fn name(&self) -> &'static str

Stable, lowercase identifier for the source (e.g. "youtube"). Used in error messages, the Transcript::source field, and as the CLI subcommand name.

Source

fn matches(url: &str) -> bool
where Self: Sized,

Whether this source recognises url as one of its locators. Used by future auto-detection (omni-dev transcript fetch <url>).

where Self: Sized keeps this method out of the dyn vtable so dyn TranscriptSource remains object-safe.

Source

fn fetch<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, locator: &'life1 str, opts: &'life2 FetchOpts, ) -> Pin<Box<dyn Future<Output = Result<Transcript>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Resolve locator to a transcript matching opts.

Source

fn list_languages<'life0, 'life1, 'async_trait>( &'life0 self, locator: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<LanguageInfo>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

List the caption tracks available on locator.

Source

fn info<'life0, 'life1, 'async_trait>( &'life0 self, locator: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<MediaInfo>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Fetch top-level metadata about locator.
