1//! Stubs for features that are disabled
2
3/// Creates an optional config.
4///
5/// For a config parser that implements `ConfigParser`, one should add the parser to this features file
6/// in order to allow it to be disabled or enabled through the features.
7///
8/// This macro takes three parameters. The first of these is the feature as a string literal. This means
9/// that whatever your feature is called (such as bls), it should be wrapped in double quotes as though
10/// it were a string literal, like "bls".
11/// The second is the feature as an identifier, and should be the name of the configuration parser module.
12/// This should be the same as the previous parameter, without double quotes as it is not a string literal.
13/// The third is the name of the config struct that implements `ConfigParser`. This can be named something like
14/// `BlsConfig`.
15/// The final macro invocation should look something like `optional_config!("bls", bls, BlsConfig)`.
