Enum Error 

#[non_exhaustive]
pub enum Error {
    PriorityElevation(String),
    MidiInit(String),
    PortNotFound {
        name: String,
    },
    QueueFull,
    ThreadPanicked,
    AlreadyStopped,
}

Errors that can occur during real-time MIDI operations.

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.

PriorityElevation(String)

Failed to elevate the RT thread to real-time priority.

MidiInit(String)

MIDI subsystem initialization failed.

PortNotFound

A requested MIDI port could not be found by name.

Fields

name: String

The name that was searched for.

QueueFull

The RT-to-ECS lock-free queue is full; events are being dropped.

ThreadPanicked

The RT thread panicked and is no longer running.

AlreadyStopped

Attempted to stop or interact with a runtime that has already stopped.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
