1//! Zero-dependency QR code encoding core (`no_std` + `alloc`) for `qrcode-rs`.
2//!
3//! Holds the encoding primitive layer — bit-stream construction ([`bits::Bits`]),
4//! mode optimization ([`optimize`]), Reed–Solomon error correction ([`ec`]),
5//! and module-grid canvas drawing ([`canvas`]) — plus the shared types
6//! ([`types`]) and checked-cast helpers ([`cast`]), with no external crate
7//! dependencies. The `qrcode-rs` facade crate depends on this and re-exports
8//! its public surface; embedders wanting only the encoder (no rendering or
9//! image dependencies) can depend on `qrcode-core` directly.
