}

Errors that can occur during transcript fetching, parsing, or formatting.

Variants

InvalidLocator(String)

The supplied locator (URL, ID) could not be parsed by any source.

ParseError(String)

The media platform returned a response that did not parse as expected.

LanguageNotFound

No caption track matched the requested language.

Fields

requested: String

The language code the caller asked for.

available: Vec<String>

Language codes that are available on the media item.

AutoCaptionsRequireOptIn(String)

An auto-generated (asr) track was the only match but the caller did not opt in via allow_auto.

PlayabilityRefused

The media platform refused playback (e.g. age-gated, region-locked, removed, or login-required). Carries the platform’s status string so callers can react to the specific reason rather than a generic HTTP failure.

Fields

status: String

Platform-specific status code (e.g. YouTube LOGIN_REQUIRED, AGE_VERIFICATION_REQUIRED, UNPLAYABLE).

reason: Option<String>

Optional human-readable reason from the platform.

Io(Error)

An I/O error occurred (e.g. writing transcript to a file).

Http(Error)

An HTTP transport or non-2xx response error.

MissingVisitorData

The bootstrap GET to a media platform’s watch page returned a body without the expected session-bootstrap token. The page format drifts every few months; this variant signals the scrape needs to be retuned and is distinct from a generic Self::ParseError so callers can react to it specifically (e.g. a clearer CLI message).

Fields

url: String

The URL whose response body was scraped.

Trait Implementations

impl Debug for TranscriptError

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

Formats the value using the given formatter.

impl Display for TranscriptError

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

Formats the value using the given formatter.

impl Error for TranscriptError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for TranscriptError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for TranscriptError

fn from(source: Error) -> Self
