Struct Error 

pub struct Error { /* private fields */ }

The error type for all fallible operations in edgefirst-tflite.

Error wraps a private ErrorKind enum so that the set of failure modes can grow without breaking callers. Use the is_*() inspection methods and Error::status_code to classify an error programmatically.

Implementations

impl Error

pub fn is_library_error(&self) -> bool

Returns true if this error originated from library loading or symbol resolution (i.e. a libloading::Error).

pub fn is_delegate_error(&self) -> bool

Returns true if the underlying TFLite status is one of the delegate error codes: StatusCode::DelegateError, StatusCode::DelegateDataNotFound, StatusCode::DelegateDataWriteError, or StatusCode::DelegateDataReadError.

pub fn is_null_pointer(&self) -> bool

Returns true if a C API call returned a null pointer.

pub fn is_invalid_argument(&self) -> bool

Returns true if this error is an invalid-argument error.

pub fn status_code(&self) -> Option<StatusCode>

Returns the TFLite StatusCode when the error originated from a non-OK C API status, or None otherwise.

pub fn with_context(self, context: impl Into<String>) -> Self

Attach additional human-readable context to this error.

The context string is appended in parentheses when the error is displayed.

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, f: &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(err: Error) -> Self

Converts to this type from the input type.
