Enum Error 

pub enum Error {
    Spawn {
        cmd: &'static str,
        source: Error,
        path: String,
    },
    DiscoverParse(String),
    DiscoverFailed {
        path: PathBuf,
        stderr: String,
    },
    Io(Error),
}

Failure modes for the gstreamer-pipe decoder.

Variants

Spawn

gst-launch-1.0 or gst-discoverer-1.0 could not be launched. Almost always means the GStreamer CLI tools aren’t on PATH. The error message includes the current PATH value so CI logs surface the exact lookup state for diagnosis.

Fields

cmd: &'static str

The command we tried to spawn.

source: Error

The OS-level reason the spawn failed.

path: String

Snapshot of PATH at the moment of failure.

DiscoverParse(String)

gst-discoverer-1.0 returned non-parseable output.

DiscoverFailed

gst-discoverer-1.0 returned an error exit code.

Fields

path: PathBuf

The video path we asked about.

stderr: String

Captured stderr.

Io(Error)

I/O error while reading the pipe.

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.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
