ttf-parser

A high-level, safe, zero-allocation TrueType font parser.

Goals

• A high-level API.
• Zero allocations.
• Zero unsafe.
• Zero dependencies.
• Fast.
• Simple and maintainable code (no magic numbers).

Limitations

• Non [ARGSAREXY_VALUES] transform is not supported yet.
• Only 0, 4, 12 and 13 formats of cmap table are supported.

Safety

• The library heavily relies on Rust's bounds checking and assumes that font is well-formed. You can invoke a checksums checking manually.
• The library uses per table slices, so it can't read data outside the specified TrueType table.
• The library forbids unsafe code.

Alternatives

• font-rs - Mainly a glyph outline extractor. No documentation. Has less features. A lot of magic numbers.
• truetype - Isn't allocation free. Does a little postprocessing (parses most of the data as is). Has some unsafe.
• stb_truetype - Mainly a glyph outline extractor. Isn't allocation free. Has less features. Uses panic a lot.
