Expand description
A high-level, safe, zero-allocation TrueType font parser.
§Features
- A high-level API, for people who doesn’t know how TrueType works internally. Basically, no direct access to font tables.
- Zero heap allocations.
- Zero unsafe.
- Zero dependencies.
no_std/WASM compatible.- Fast.
- Stateless. All parsing methods are immutable methods.
- Simple and maintainable code (no magic numbers).
§Safety
- The library must not panic. Any panic considered as a critical bug and should be reported.
- The library forbids the unsafe code.
- No heap allocations, so crash due to OOM is not possible.
- All recursive methods have a depth limit.
- Technically, should use less than 64KiB of stack in worst case scenario.
- Most of arithmetic operations are checked.
- Most of numeric casts are checked.
