Crate 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 ARGS_ARE_XY_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.
