Collection of libraries offering lexicographically-sortable ULIDs, zero-overhead 64-bit BitSet with bitwise ops and set-bit iteration, and unified asynchronous file I/O including OPFS support.
A collection of Kotlin Multiplatform libraries targeting JVM, Android, Native, and web (JS/WASM) platforms. All libraries are published to Maven Central under the com.bitgrind.kmp group.
| Library | Version | Description |
|---|---|---|
| ulid | Lexicographically sortable, monotonic, cryptographically random IDs — 26-char Crockford Base32 encoding of a 48-bit timestamp + 80-bit random component | |
| structs | Zero-overhead data structures; currently a 64-bit inline BitSet with full bitwise ops and set-bit iteration | |
| filestorage | Unified async file I/O API with native browser support using OPFS. |
All libraries share the same target matrix:

| Platform | Target |
|---|
| JVM 21 | jvm |
| Android (minSdk 28) | androidTarget |
| Linux x86-64 | linuxX64 |
| JavaScript / Browser | js (ES2015 modules + TypeScript definitions) |
| WebAssembly / Browser | wasmJs (ES2015 + TypeScript definitions) |
Surfaced from shared tags and platforms — no rankings paid for.
