Enum jq_rs::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

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 of System

reason: Option<String>

Feedback from jq about what went wrong, when available.

StringConvert

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

Fields of StringConvert

err: Box<dyn Error + 'static>

The original error which lead to this.

Unknown

Something bad happened, but it was unexpected.
