oxisqlite-macros

Procedural macros backing the extension API of the C-free oxisqlite engine — a Pure-Rust fork of limbo 0.0.22, internal to the OxiSQL workspace.

This crate implements the proc-macros that the oxisqlite-ext extension API is built on:

• the scalar attribute macro (scalar SQL functions),

• AggregateDerive (aggregate SQL functions),

• VTabModuleDerive (virtual tables),

• VfsDerive (VFS modules), and

• the register_extension! function-like macro that wires the above into the engine.

• Role: proc-macros for the oxisqlite extension API.

• Approx LOC: ~900.

• Pure Rust / no C: 100% Rust. No C allocator, no C parser generator, no cc / build.rs.

• Internal: private member of the OxiSQL workspace; not published separately.

COOLJAPAN change vs upstream limbo

The registration macro no longer injects a non-static #[global_allocator] (upstream wired in a C allocator there for dynamically-loaded extensions). That injection was removed so the fork stays C-free; registering an extension pulls in no C allocator and no global-allocator override.
