Struct FileEncoder

pub struct FileEncoder { /* private fields */ }

FileEncoder encodes data to file via fixed-size buffer.

There used to be a MemEncoder type that encoded all the data into a Vec. FileEncoder is better because its memory use is determined by the size of the buffer, rather than the full length of the encoded data, and because it doesn’t need to reallocate memory along the way.
