Struct TTF_TextEngine 

#[repr(C)]
pub struct TTF_TextEngine {
    pub version: Uint32,
    pub userdata: *mut c_void,
    pub CreateText: Option<unsafe extern "C" fn(userdata: *mut c_void, text: *mut TTF_Text) -> bool>,
    pub DestroyText: Option<unsafe extern "C" fn(userdata: *mut c_void, text: *mut TTF_Text)>,
}

A text engine used to create text objects.

This is a public interface that can be used by applications and libraries to perform customize rendering with text objects. See <SDL3_ttf/SDL_textengine.h> for details.

There are three text engines provided with the library:

• Drawing to an SDL_Surface, created with TTF_CreateSurfaceTextEngine()
• Drawing with an SDL 2D renderer, created with TTF_CreateRendererTextEngine()
• Drawing with the SDL GPU API, created with TTF_CreateGPUTextEngine()

Availability

This struct is available since SDL_ttf 3.0.0. A text engine interface.

This structure should be initialized using SDL_INIT_INTERFACE()
