The Ptah Wire Format

The wire format describes how messages can be encoded into a stream of bytes suitable for transmission over a channel, or over another transport layer such as the network or a serial port.


Primitives are transmitted as little-endian and packed to their natural alignment. The following primitive types are recognised:

NameSize (bytes)Description
bool1A boolean value
u8, u16, u32, u64, u1281, 2, 4, 8An unsigned integer
i8, i16, i32, i64, i1281, 2, 4, 8A signed integer
f32, f644, 8Single / double-precision IEEE-754 FP values
char4A single UTF-8 Unicode scalar value
