"WebSerialization format: - Each field is serialized in order, by calling from_bytes/__bytes__. - For Lists, there is a 4 byte prefix for the list length. - For Optionals, there is a one byte prefix, 1 iff object is present, 0 iff not. All of the constituents must have parse/from_bytes, and stream/__bytes__ and therefore be of fixed size. " - How many bytes is int8_t

WebIn code ported from other platforms, especially 8-bit or 16-bit platforms, the data types may have had different sizes. For example, int may have been represented as 16-bits. If this size has been relied on, some of the code may need updating to make it more portable. WebFeb 2, 2024 · The character, integer, and Boolean types are common to most C compilers.
