Struct AutoMapEnvArgs 

pub struct AutoMapEnvArgs<'a> {
    pub divider: &'a str,
    pub prefix: Option<&'a str>,
    pub transform: Box<dyn Fn(&str) -> String>,
}

Automatically map environment variables into config.

Fields

divider: &'a str

The divider that separates different levels of the parent.child relationship for the mapping. This will get replaced with . when converting the name of a variable to a TomlKeyPath. The default value is DEFAULT_DOTENV_PATH.

prefix: Option<&'a str>

Prefix for environment variables to be mapped. By default this will be DEFAULT_CONFIG_VARIABLE_NAME.

transform: Box<dyn Fn(&str) -> String>

A transform operation to perform on the environment variable before parsing it. By default this transforms it to lowercase.
