Enum GraphStateError 

#[non_exhaustive]
pub enum GraphStateError {
    Topology,
    ClipChain {
        bus: usize,
        error: ChainStateError,
    },
    TrackBus {
        bus: usize,
        error: ChainStateError,
    },
    Master(ChainStateError),
    Alignment {
        bus: usize,
        error: StateError,
    },
}

Where an AudioGraph refused a saved state, and why. The graph is left as it was.

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.

Topology

The state was saved by a graph with another number of buses.

ClipChain

A bus’s clip chain refused its part.

Fields

bus: usize

The bus.

error: ChainStateError

Where in the chain, and why.

TrackBus

A track bus refused its part.

Fields

bus: usize

The bus.

error: ChainStateError

Where in the chain, and why.

Master(ChainStateError)

The master chain refused its part.

Alignment

The audio a bus’s alignment holds does not fit it: the buses’ latencies differ from the saving graph’s.

Fields

bus: usize

The bus.

error: StateError

Why.

Trait Implementations

impl Eq for GraphStateError

impl Error for GraphStateError

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 PartialEq for GraphStateError

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

Equality operator ==.

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

Inequality operator !=.
