Struct LoaderContext 

pub struct LoaderContext<'a> {
    pub loader_type: Option<&'a LoaderType>,
    pub version_id: Option<&'a str>,
    pub extra_game_args: &'a [String],
    pub extra_jvm_args: &'a [String],
}

Context contributed by the active mod loader for argument building. Constructed in launcher/mod.rs from the stored GameData fields.
