Enum StartError

pub enum StartError {
    Buffer,
    Pipeline,
    Link,
    Generic(Error),
}

Contains errors returned by the STREAMON call. The error is not created to make handling easier, but instead to describe the problem to the user in an informative way.

Variants

Buffer

The buffer type is not supported, or no buffers have been allocated (memory mapping) or enqueued (output) yet.

Pipeline

The driver implements pad-level format configuration and the pipeline configuration is invalid.

Link

The driver implements Media Controller interface and the pipeline link configuration is invalid.

Generic(Error)

Any other error

Trait Implementations

impl Debug for StartError

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

Formats the value using the given formatter.

impl Display for StartError

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

Formats the value using the given formatter.

impl Error for StartError

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 From<Error> for StartError

fn from(value: Error) -> Self

Converts to this type from the input type.

impl From<StartError> for Error

fn from(value: StartError) -> Self

Converts to this type from the input type.
