Struct mupdf_sys::fz_shaper_data_t

#[repr(C)]pub struct fz_shaper_data_t {
    pub shaper_handle: *mut c_void,
    pub destroy: Option<unsafe extern "C" fn(ctx: *mut fz_context, arg1: *mut c_void)>,
}

In order to shape a given font, we need to declare it to a shaper library (harfbuzz, by default, but others are possible). To avoid redeclaring it every time we need to shape, we hold a shaper handle and the destructor for it within the font itself. The handle is initialised by the caller when first required and the destructor is called when the fz_font is destroyed.

Fields

shaper_handle: *mut c_void

destroy: Option<unsafe extern "C" fn(ctx: *mut fz_context, arg1: *mut c_void)>
