Enum EimError

pub enum EimError {
    FileError(Error),
    InvalidPath,
    ExecutionError(String),
    SocketError(String),
    JsonError(Error),
    InvalidInput(String),
    InvalidOperation(String),
}

Represents all possible errors that can occur in the Edge Impulse Runner.

This enum implements the standard Error trait using thiserror and provides detailed error messages for each error case. It handles both internal errors and wrapped errors from external dependencies.

Variants

FileError(Error)

Indicates a failure in file system operations when accessing the EIM file.

This error occurs when there are problems reading, writing, or accessing the model file. It wraps the standard IO error for more details.

InvalidPath

Indicates that the provided path to the EIM file is invalid.

This error occurs when:

• The path doesn’t exist
• The file extension is not .eim
• The path points to a directory instead of a file

ExecutionError(String)

Indicates a failure during model execution.

This error occurs when:

• The model process crashes
• The model fails to initialize
• There’s an internal model error during inference

SocketError(String)

Indicates a failure in Unix socket communication.

This error occurs when:

• The socket connection fails
• Messages can’t be sent or received
• The socket connection is unexpectedly closed

JsonError(Error)

Indicates a failure in JSON serialization or deserialization.

This error occurs when:

• Messages can’t be encoded to JSON
• Responses can’t be decoded from JSON
• The JSON structure doesn’t match expected schema

InvalidInput(String)

Indicates that the provided input data is invalid.

This error occurs when:

• Input features don’t match expected dimensions
• Input values are out of valid ranges
• Required input parameters are missing

InvalidOperation(String)

Indicates that an invalid operation was attempted.

This error occurs when:

• Operations are called in wrong order
• Unsupported operations are requested
• Operation parameters are incompatible

Trait Implementations

impl Debug for EimError

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

Formats the value using the given formatter.

impl Display for EimError

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

Formats the value using the given formatter.

impl Error for EimError

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 EimError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for EimError

fn from(source: Error) -> Self

Converts to this type from the input type.
