Expand description

Block descriptor that contains copy and dispose operations.

Requires BLOCK_HAS_COPY_DISPOSE

Fields

header: Block_descriptor_headercopy: Option<unsafe extern "C" fn(dst: *mut c_void, src: *mut c_void)>

Copy function, generated by the compiler to help copy the block if it contains nontrivial copy operations.

dispose: Option<unsafe extern "C" fn(src: *mut c_void)>

Dispose function, generated by the compiler to help copy the block if it contains nontrivial destructors.
