bymsdfgen_core/lib.rs
1//! # bymsdfgen-core
2//!
3//! The core crate of `bymsdfgen`, a **pure-Rust msdf generator** and pure-Rust
4//! alternative to msdfgen: generation of conventional and multi-channel signed
5//! distance fields from vector shapes, with no C++ toolchain and no FFI.
6//!
7//! Design highlights versus the C++ original:
8//! - **Zero-cost dispatch**: edges are a `Copy` [`geometry::EdgeSegment`] enum
9//! (`match`) instead of a virtual class hierarchy behind heap pointers.
10//! - **Data-oriented layout**: contours store segments in flat, contiguous `Vec`s.
11//! - **Typed coordinate spaces**: [`math::typed`] newtypes make space mismatches a
12//! compile error rather than a silent logic bug.
13//! - **Fearless parallelism**: row-parallel generation via rayon (feature
14//! `parallel`) with compile-time data-race freedom.
