Errors returned by the safe vmb wrapper.

Variants

Sdk

A non-success return code from a VmbC call.

Fields

code: i32

The raw VmbError_t return code.

message: String

A short description of which call failed.

NotStarted

The Vimba runtime has not been started, or was already shut down.

AlreadyStarted

Attempted to start the Vimba runtime while a previous VmbSystem instance is still alive. The runtime is process-global and the wrapper enforces a singleton invariant.

Io

I/O failure while reading a settings XML file (or a related path).

Fields

path: PathBuf

The offending path.

source: Error

The underlying std::io::Error.

InvalidString

A string supplied by the SDK or by the caller was not valid UTF-8 or contained an interior nul byte.

Fields

context: &'static str

A static label identifying which string was rejected.

CaptureAlreadyRunning

Camera::start_capture was called while a previous capture is still running on the same camera.

FrameTooSmall

A received frame was smaller than expected for its declared format.

Fields

expected: usize

The declared/expected byte count.

actual: usize

The actual byte count delivered by the SDK.

LoadFailed

Failed to load the Vimba X shared library at runtime, or resolve one of its symbols. Typically surfaced from VmbFfiRuntime::new when the SDK is not installed on the host.

Fields

message: String

Human-readable description of the loader failure, including the path(s) tried and the underlying OS error.

Trait Implementations

impl Debug for VmbError

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

Formats the value using the given formatter.

impl Display for VmbError

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

Formats the value using the given formatter.

impl Error for VmbError

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.
