Function SDL_CopyGPUTextureToTexture 

pub unsafe extern "C" fn SDL_CopyGPUTextureToTexture(
    copy_pass: *mut SDL_GPUCopyPass,
    source: *const SDL_GPUTextureLocation,
    destination: *const SDL_GPUTextureLocation,
    w: Uint32,
    h: Uint32,
    d: Uint32,
    cycle: bool,
)

Performs a texture-to-texture copy.

This copy occurs on the GPU timeline. You may assume the copy has finished in subsequent commands.

This function does not support copying between depth and color textures. For those, copy the texture to a buffer and then to the destination texture.

Parameters

• copy_pass: a copy pass handle.
• source: a source texture region.
• destination: a destination texture region.
• w: the width of the region to copy.
• h: the height of the region to copy.
• d: the depth of the region to copy.
• cycle: if true, cycles the destination texture if the destination texture is bound, otherwise overwrites the data.

Availability

This function is available since SDL 3.2.0.
