Trait io_providers::Io[−][src]

pub trait Io {
    type E: Env;
    type F: Fs;
    type S: StdStreams;
    fn env(&self) -> &Self::E;
    fn env_mut(&mut self) -> &mut Self::E;

    fn fs_mut(&mut self) -> &mut Self::F;
    fn std_streams(&mut self) -> &mut Self::S;
}

Provides access to the process environment, filesystem, and standard streams.

See env::Env, std_streams::StdStreams and fs::Fs for details.
