xc3_write

xc3_lib binary writing and layout. See Offsets for a high level overview.

lib.rs:

A binary writing and layout implementation using separate write and layout passes.

An object's size is defined as the difference between the writer position before and after the first pass and does not need to be user defined. Custom implementations of [Xc3Write] should ensure the write head points after the data when the function returns to ensure correct size calculations.
