Enum DecoderBackend 

#[non_exhaustive]
pub enum DecoderBackend {
    Symphonia,
}

Explicit backend selection for DecoderFactory.

Replaces the legacy boolean prefer_hardware flag with a typed enum so callers spell out which backend they want. Failures of the selected backend are terminal — there is no fallback chain.

Variants are gated on cargo features: a hardware variant exists in the type only when its platform feature is enabled (and only on a matching target_os). Picking DecoderBackend::Apple on Linux is therefore a compile error, not a runtime BackendUnavailable.

Default = DecoderBackend::Symphonia: the software path is cross-platform and capability-complete (gapless seek, full StreamContext propagation). Hardware backends (Apple/Android) are opt-in — there is no runtime fallback.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Symphonia

Symphonia software decoder (cross-platform, requires the symphonia feature).

Trait Implementations

impl Clone for DecoderBackend

fn clone(&self) -> DecoderBackend

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DecoderBackend

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

Formats the value using the given formatter.

impl Default for DecoderBackend

fn default() -> DecoderBackend

Returns the “default value” for a type.

impl Display for DecoderBackend

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

Formats the value using the given formatter.

impl PartialEq for DecoderBackend

fn eq(&self, other: &DecoderBackend) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
