Enum Source

pub enum Source {
    ConfigFiles(Vec<FileOptions>),
    Clap(ClapSource),
    Env(HashMap<String, String>),
}

Replacement of the usual source to find values for the fields.

Variants

ConfigFiles(Vec<FileOptions>)

Configuration files.

Note: It is allowed to specify multiple files: all of them will be merged. If there is a collision (the values of a particular key have been specified in two or more files), the value will be assigned from the file that has been described later.

Clap(ClapSource)

Command line source.

Env(HashMap<String, String>)

Map that replaces the enviromnent (fields, annotated with #[source(env)] will be searched in this map).

Can be useful in testing.
