Trait Config 

pub trait Config {
    type Id;

    const CODE: Option<&'static str> = None;

    // Provided methods
    fn id() -> Option<Self::Id> { ... }
    fn display<C: Config, D>(gerr: &GErr<C, D>) -> String
       where C::Id: Display,
             D: Debug { ... }
}

Error config.

Provided Associated Constants

const CODE: Option<&'static str> = None

Error code.

Required Associated Types

type Id

Error id.

Must be:

• Implementing Display & Debug.
• Implementing serde’s Serialize and Deserialize for serde feature.

Provided Methods

fn id() -> Option<Self::Id>

Auto-generate error id.

fn display<C: Config, D>(gerr: &GErr<C, D>) -> String

where C::Id: Display, D: Debug,

Display error message.

It will be invoked in Display implementation.
