std/error

std/error defines data types. It does not replace the T!E failure syntax or require application-specific errors to use this representation.

import "std/error" as error;

var problem = error.Error {
    kind: error.ErrorKind.NotFound,
    code: 2,
    message: "configuration not found",
};

Types

pub enum ErrorKind {
    Unknown,
    NotFound,
    PermissionDenied,
    InvalidInput,
    AlreadyExists,
    Io,
}

pub struct Error {
    kind: ErrorKind,
    code: Int,
    message: String,
}

Err aliases Error, and Kind aliases ErrorKind.

For failures in your own API, choose an @error enum, @error struct, or @error class according to the data and behavior callers need. See Error handling.
