A set of small packages that aren't worth their own repositories but are still useful and used across the projects
Ordinary buffer with pre-allocated (but dynamically-growing up to upper limit) storage for values. The only difference between it and, to say, bytes.Buffer, is that it contains markers. This isn't a lot of code neither difficult, but this found its application all across the indigo by itself (primarily http parser with header keys and values) and some other cross-projects.
A small set of generic annotations.
Functional Tools: map, reduce, summer. Yet another fp-tools library without even tests.
Provides functions to validate hex characters, and one for decoding byte sequence.
Contains Keys and Copy map operations. Ain't much but it's honest work.
Simple thread-unsafe object-pool. Wrote own implementation as too lazy to benchmark the one from std-library and compare them (thread-safety is anyway not needed, so considered by me to be an overkill).
Contains a single function - EqualFold(). It compares case-insensitively two equal-length strings char-by-char.
Small package with common and widely used (at least in indigo and some other side projects) unsafe functions B2S and S2B. The implementation is taken from fasthttp.
Save unneeded bytes for the next time. Used mostly to leave data read from socket for future.
