Example Code

The example from chapter 7 of RFC4506 can be represented in Rust like so:

#[repr(u32)]
enum FileType {
    Text,
    Data { creator: String },
    Exec { interpretor: String },
}

#[derive(Debug, Facet, PartialEq)]
struct File {
    filename: String,
    filetype: FileType,
    owner: String,
    data: Vec<u8>,
}
