Enum Error 

pub enum Error {
    NoInputDevice,
    DeviceNotFound {
        wanted: String,
        available: String,
    },
    UnsupportedInput {
        wanted: u32,
        offered: String,
    },
    Capture {

    },
}

What a host could not do with the microphone.

Variants

NoInputDevice

The host has no default input device at all.

DeviceNotFound

A named device is not present. The alternatives are listed because a person who picked an interface needs the answer to “what is there”.

Fields

wanted: String

The id the caller asked for.

available: String

The devices that are present, as id (name) pairs.

UnsupportedInput

The device offers no stream in a format this crate can open.

The sentence leads with the FORMATS and names the rate second: an I16-only device refused by a rate sentence sent a reader after a sample-rate problem that was never there (#2362).

Fields

wanted: u32

The rate the caller needed.

offered: String

What the device offered, so the mismatch is legible.

Capture

The stream could not be opened, configured or started.

Fields

message: String

The host’s own words for the failure.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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.
