Enum LibmagicError 

pub enum LibmagicError {
    ParseError(ParseError),
    EvaluationError(EvaluationError),
    IoError(Error),
    Timeout {
        timeout_ms: u64,
    },
    ConfigError {
        reason: String,
    },
    FileError(String),
}

Main error type for the libmagic-rs library.

This enum represents all possible errors that can occur during magic file parsing, rule evaluation, and file I/O operations.

Variants

ParseError(ParseError)

Error that occurred during magic file parsing.

EvaluationError(EvaluationError)

Error that occurred during rule evaluation.

IoError(Error)

I/O error that occurred during file operations.

Timeout

Evaluation timeout exceeded.

Fields

timeout_ms: u64

The timeout duration in milliseconds

ConfigError

Invalid configuration parameter.

Examples

use libmagic_rs::LibmagicError;

let error = LibmagicError::ConfigError {
    reason: "invalid timeout value".to_string(),
};
assert!(matches!(error, LibmagicError::ConfigError { .. }));

Fields

reason: String

Description of the configuration issue

FileError(String)

File I/O error with structured context (path, operation).

Unlike IoError which wraps a generic std::io::Error, this variant preserves the structured error information from file I/O operations (e.g., file path, operation type).

Examples

use libmagic_rs::LibmagicError;

let error = LibmagicError::FileError("failed to read /path/to/file".to_string());
assert!(matches!(error, LibmagicError::FileError(_)));

Trait Implementations

impl Debug for LibmagicError

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

Formats the value using the given formatter.

impl Display for LibmagicError

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

Formats the value using the given formatter.

impl Error for LibmagicError

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.
