codec v0.1.2 Codec.BinType
Link to this section Summary
Functions
Used in encoder/decoder definitions. Adds a bit shift in order to byte-justify the leading bits in a bit field that spans multiple bytes and needs to be little endian encoded. For example, suppose we have a bit field of << 0x0A, 0xBC >>. Without add_shift, if we throw away the 0 and then create a 12 bit field with the remaining bits, we will end up with a little endian reassembly of 0x0CAB. If we add_shift(4) to the 8 bit field for 0xBC, we can then have 0xBC0A. Which interpretation is correct depends upon the particular parser being created
Used in encoder/decoder definitions by the encoder maker for executing special functions on the encoded block. They take the form: call_on_encoded(:function_atom, [:before || :after]) :function_atom is the name of a function that takes a byte array and returns some type of integer that can be added to the output byte stream. :before and :after are used to declare whether the results of the called function are placed at the beginning(:before) of the byte stream or at the rear(:after)
Used in encoder/decoder definitions by the encoder maker for choosing a default for a given field. That default is used to populate the struct created for the encoder
Used in encoder/decoder definitions by the encoder maker for executing special functions within the body of the encoder
