luaur-analysis 0.1.3

Luau type checker and type inference (Rust).
Documentation
//! Source: `Analysis/src/AstJsonEncoder.cpp:89-1052` (hand-ported)
//! C++ resolves `write(propName, value)` by overload on the static type of
//! `value`; Rust resolves it through `WriteJson`. One impl per C++ overload,
//! each delegating to the inherent method holding that overload's body.
//! Base-node pointers go through `write(AstNode*) = node->visit(this)`
//! (AstJsonEncoder.cpp:271); concrete-node pointers bind their concrete
//! overload exactly as C++ overload resolution does.
