## What it is
A native Go implementation of the MurmurHash3 non-cryptographic hash function, supporting both 32-bit and 128-bit variants. It implements Go's standard hash.Hash interface with streaming mode support.

## Use cases
- compute murmur3 hashes in Go
- hash data for bloom filters
- generate fast non-cryptographic checksums
- implement consistent hashing or hash tables
- stream large inputs through a hash function

## When to choose
- you need MurmurHash3 compatibility in a Go project
- you want a fast, dependency-free non-cryptographic hash
- you need streaming hashing via Go's hash.Hash interface

## When to avoid
- you need a cryptographic hash for security purposes
- you are not working in Go
- you need actively developed features beyond the core algorithm

## Facets
- artifact type: library
- maturity: maintenance
- function: serialization, developer-tools
- domain: developer-tools, databases
- platform: go, cross-platform
- tags: murmurhash3, hashing, non-cryptographic-hash, streaming-hash, algorithms
