Module encode 

CdrEncode / CdrDecode traits + primitive implementations (W1.3).

Trait-based instead of free functions, so that composite types in W2/W3 can recursively encode their children uniformly without large type switches.

Alignment convention

• u8/i8/bool: 1
• u16/i16: 2
• u32/i32/f32/char: 4
• u64/i64/f64: 8

Char is encoded as XCDR2 wchar32 (4 bytes) (OMG XTypes §7.4.7); that covers full Unicode. The XCDR1 char variant (1 byte ASCII) lives in the separate xcdr1 module (see the crate header).

Traits

CdrDecode

Value can be decoded from a BufferReader.

CdrEncode

Value can be encoded into a BufferWriter.
