Enum Error

pub enum Error {
    InvalidProgram,
    System {
        reason: Option<String>,
    },
    StringConvert {
        err: Box<dyn Error + 'static>,
    },
    Unknown,
}

There are many potential causes for failure when running jq programs. This enum attempts to unify them all under a single type.

Variants

InvalidProgram

The jq program failed to compile.

System

System errors are raised by the internal jq state machine. These can indicate problems parsing input, or even failures while initializing the state machine itself.

Fields

reason: Option<String>

Feedback from jq about what went wrong, when available.

StringConvert

Errors encountered during conversion between CString/String or vice versa.

Fields

err: Box<dyn Error + 'static>

The original error which lead to this.

Unknown

Something bad happened, but it was unexpected.

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 description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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<NulError> for Error

fn from(err: NulError) -> Self

Converts to this type from the input type.

impl From<Utf8Error> for Error

fn from(err: Utf8Error) -> Self

Converts to this type from the input type.

impl Send for Error
