Struct VariantChangeError 

pub struct VariantChangeError;

Non-retriable cross-variant boundary signal — the typed payload of the io::Error produced by impl Read for Stream when the underlying source fenced on a variant change. Decoders that go through std::io::Read (Symphonia chain walker) downcast on this type to recover the precise classification without string-matching.

Trait Implementations

impl Clone for VariantChangeError

fn clone(&self) -> VariantChangeError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VariantChangeError

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

Formats the value using the given formatter.

impl Display for VariantChangeError

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

Formats the value using the given formatter.

impl Error for VariantChangeError

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.
