Crate ttf_parser
source · [−]Expand description
A high-level, safe, zero-allocation TrueType font parser.
Supports TrueType, OpenType and AAT fonts.
Font parsing starts with a Face.
Features
- A high-level API for most common properties, hiding all parsing and data resolving logic.
- A low-level, but safe API to access TrueType tables data.
- Highly configurable. You can disable most of the features, reducing binary size. You can also parse TrueType tables separately, without loading the whole font/face.
- Zero heap allocations.
- Zero unsafe.
- Zero dependencies.
no_std/WASM compatible.- Fast.
- Stateless. All parsing methods are immutable.
- 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 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.
