Enum SourcePhase 

#[non_exhaustive]
pub enum SourcePhase {
    Cancelled,
    Eof,
    Ready,
    Seeking,
    Waiting,
    WaitingDemand,
    WaitingMetadata,
}

Phase of a source’s wait/read lifecycle.

Each Source implementation returns the current phase from its phase() method — a point-in-time snapshot for external observers (audio pipeline, tracing, UI).

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.

Cancelled

Cancelled — terminal, source will not produce more data.

Eof

End of stream reached.

Ready

Requested range is available for non-blocking read.

Seeking

Active seek in progress — decoder should be interrupted.

Waiting

Default: data not yet available, no specific sub-state.

WaitingDemand

On-demand request already in flight for this seek epoch.

WaitingMetadata

Metadata lookup needed before data can be requested.

Trait Implementations

impl Clone for SourcePhase

fn clone(&self) -> SourcePhase

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SourcePhase

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

Formats the value using the given formatter.

impl Default for SourcePhase

fn default() -> SourcePhase

Returns the “default value” for a type.

impl PartialEq for SourcePhase

fn eq(&self, other: &SourcePhase) -> 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.

impl Copy for SourcePhase

impl Eq for SourcePhase

impl StructuralPartialEq for SourcePhase
