bitbuffer

Bit level manipulation of buffers 😎

1:1 recreation of the buffer api for the bit level, includes all functions except len, create, tostring and fromstring, as there is no use for a bit level counterpart.

writeu and writei allows for widths ranging from 1 to 53. Writing an i53 doesn't use 2's compliment for the format, due to f64 precision issues.

If you want to use a combined byte/bit offset, you can merley use this idiv and mod to separate it when calling the function bitbuffer.writeu(b, offset // 8, offset % 8, value), the reason this isn't done internally is to allow for extra micro-optimization when using this module. Other ways to handle offsets are included here.

Can be installed with wally using arvidsilverlock/bitbuffer@latest

Current Version - 0.1.2

Changes since the previous version include:

• Inlining writeu and readu functions when used internally (except for Reader and Writer classes)
• Inlining IncrementOffset within Reader and Writer classes.
• Removal of the localisation of buffer.read calls, this has no effect on performance.
• Adding an Offset class which handles your offset for you, Reader and Writer inherit from this.
• The buffer, byte and bit values present in Readers and Writers are no longer considered private.
