cdumay_error

cdumay_error is a basic library used to standardize errors and serialize them using serde.

Quickstart

Cargo.toml:

[dependencies]
cdumay_error = { git = "https://github.com/cdumay/rust-cdumay_error" }
serde_json = "1.0"

main.rs:

extern crate cdumay_error;
extern crate serde_json;

fn main() {
    use cdumay_error::{ErrorRepr, GenericErrors};
    use std::collections::BTreeMap;
    use serde_json::Value;

    let mut err = ErrorRepr::from(GenericErrors::GENERIC_ERROR);
    err.message = "This is a useless generic error.".to_string();
    err.extra = Some({
        let mut extra = BTreeMap::new();
        extra.insert("context".into(), Value::String("Example".to_string()));
        extra
    });
    println!("{}", serde_json::to_string_pretty(&err).unwrap());
}

Output:

{
  "code": 500,
  "extra": {
    "context": "Example"
  },
  "message": "This is a useless generic error.",
  "msgid": "Err-15452"
}
