Type Alias harfbuzz_sys::hb_unicode_mirroring_func_t

pub type hb_unicode_mirroring_func_t = Option<unsafe extern "C" fn(ufuncs: *mut hb_unicode_funcs_t, unicode: hb_codepoint_t, user_data: *mut c_void) -> hb_codepoint_t>;

hb_unicode_mirroring_func_t: @ufuncs: A Unicode-functions structure @unicode: The code point to query @user_data: User data pointer passed by the caller

A virtual method for the #hb_unicode_funcs_t structure.

This method should retrieve the Bi-Directional Mirroring Glyph code point for a specified Unicode code point.

Note: If a code point does not have a specified Bi-Directional Mirroring Glyph defined, the method should return the original code point.

Return value: The #hb_codepoint_t of the Mirroring Glyph for @unicode
