Enum conch_runtime::eval::RedirectAction

pub enum RedirectAction<T> {
    Close(Fd),
    Open(Fd, T, Permissions),
    HereDoc(Fd, Vec<u8>),
}

Indicates what changes should be made to the environment as a result of a successful Redirect evaluation.

Variants

Close(Fd)

Indicates that a descriptor should be closed.

Open(Fd, T, Permissions)

Indicates that a descriptor should be opened with a given file handle and permissions.

HereDoc(Fd, Vec<u8>)

Indicates that the body of a heredoc should be asynchronously written to a file handle on a best effor basis (i.e. write as much of the body as possible but give up on appropriate errors such as broken pipes).
