Struct FramedData

pub struct FramedData {
    pub data: Vec<ByteBuf>,
}

Nix “framed data” stored in memory.

Nix has FramedSource and FramedSink for streaming large amounts of miscellaneous data. They represent lists of byte buffers, and the wire format is:

• each byte buffer is represented as a length followed by a buffer of that length. The buffer is NOT padded, unlike everything else in this protocol.
• the list is terminated by an empty buffer (which is represented on the wire as a length of zero, followed by nothing).

The whole point of this is that it is big enough that you don’t want to hold it in memory all at once. Therefore, this struct might not be ideal for “production” use; see the stream function instead.
