Enum MicError 

pub enum MicError {
    PermissionPending,
    PermissionDenied,
    DeviceBusy,
    GstFailed(String),
    NotFound(String),
}

IPC-surface error variants for the mic capture commands.

Mirror of crate::preview::CameraError. PermissionPending is the macOS first-run case where the OS shows NSMicrophoneUsageDescription and the gst pipeline blocks until the user clicks. PermissionDenied is the post-prompt rejection.

Variants

PermissionPending

macOS microphone-permission prompt is showing; no chunk has arrived yet but access isn’t denied either.

PermissionDenied

User has explicitly denied microphone access in System Settings.

DeviceBusy

The selected microphone is held by another app, or — on macOS — the missing-Info.plist failure mode that masquerades as busy.

GstFailed(String)

gst-launch pipeline spawn / runtime failure.

NotFound(String)

The picker handed us a mic_id that no longer matches any device on the host — typically the mic was unplugged between list_microphones() and start_mic_capture (Bluetooth devices sleep, USB devices yanked). Caller should re-enumerate

• re-prompt the user.

M-MIC.3 / AUT-284 + M-RECORD-EXPORT tightening — was silently falling back to autoaudiosrc, which gave the wrong device.

Trait Implementations

impl Clone for MicError

fn clone(&self) -> MicError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MicError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MicError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for MicError

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

Formats the value using the given formatter.

impl Error for MicError

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 MicError

fn eq(&self, other: &MicError) -> 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 Serialize for MicError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
