There was a problem hiding this comment.
I changed the error type to String here (like in other functions in this library that only return an error from sdl directly), but this specifically will break in an annoying way because now the error does not implement std::error::Error anymore (relevant: #942, #1053, #1424).
I feel like introducing a struct that wraps String (like pub struct SDLError(String);) and implements std::error::Error and Display. This will (in the future) also allow other enums in this crate that can contain an SDL error string to return it from std::error::Error::source.

and various other changes, including: - allow multiple `ttf::init` calls, the same way it works with TTF_Init - return last sdl error instead of I/O error (like stale pr Rust-SDL2#1348, fixes Rust-SDL2#1347 and closes Rust-SDL2#1348) - implement `Clone` for `Sdl2TtfContext`, SDL C code will do the reference counting - make `ttf::font::internal_*` `pub(super)` - make `ttf::font::Font::raw` safe (obtaining a raw pointer is safe, using it is unsafe)
