Enum ScopeKey

Source
pub enum ScopeKey {
    Application = 0,
    CLog,
    Lib,
    // some variants omitted
}
Expand description

Identifier of the Scope

This identifier is used to distinguish between different scopes in the Context. Its value is unique and used to index the Context’s Vec<Scope>.

Note: This enum is subjected to change in the future because it does not allow for dynamic scope creation. This is a limitation that should be addressed in the future.

Variants§

§

Application = 0

Application scope (default)

This scope is used for the main application and is the default scope. It should be used for the main application and its submodules. Any other scope should be used for libraries or other parts of the application.

§

CLog

Internal Logging scope

This is a reserved scope for hclog internal logging which can be enabled with HCLOG_DEBUG=1. It is not recommended to use this scope for any other purpose.

§

Lib

Scope for libraries
