fn writeUnsignedFixed(comptime l: usize, ptr: *[l]u8, int: field_call) void
[src]
This is an “advanced” function. It allows one to use a fixed amount of memory to store a ULEB128. This defeats the entire purpose of using this data encoding; it will no longer use fewer bytes to store smaller numbers. The advantage of using a fixed width is that it makes fields have a predictable size and so depending on the use case this tradeoff can be worthwhile. An example use case of this is in emitting DWARF info where one wants to make a ULEB128 field “relocatable”, meaning that it becomes possible to later go back and patch the number to be a different value without shifting all the following code.
