Struct AppError 

pub struct AppError {
    pub message: String,
    pub code: ExitCode,
    pub custom_json: Option<String>,
}

Fields

message: String

code: ExitCode

custom_json: Option<String>

Pre-serialized JSON to emit instead of the default ErrorOutput. Used by the JS execution path to preserve its richer error schema.

Trait Implementations

impl Debug for AppError

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

Formats the value using the given formatter.

impl Display for AppError

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