Enum packs::ll::types::lengths::Length

pub enum Length {
    Tiny(u8),
    Bit8(u8),
    Bit16(u16),
    Bit32(i32),
}

The possible lengths for sized types like String8. The different sign extensions are according to the PackStream specification. This type should be used for encoding any size information, e.g. the 32bit size information of a String32 or Dictionary32 can be encoded using Length:

use packs::ll::types::lengths::Length;
let mut buffer = Vec::with_capacity(4);
Length::Bit32(420420).encode(&mut buffer);

assert_eq!(buffer, vec!(0x00, 0x06, 0x6A, 0x44), "Got: {:X?}", buffer);

It does not shrink the size to any lower space (e.g. using u8 instead of i32).
