#[repr(C)]
pub struct Block_descriptor {
    pub header: Block_descriptor_header,
    pub copy: Option<unsafe extern "C" fn(dst: *mut Block_byref, src: *mut Block_byref)>,

Block descriptor that contains copy and dispose operations.

Requires BLOCK_HAS_COPY_DISPOSE

Fields

header: Block_descriptor_header

copy: Option<unsafe extern "C" fn(dst: *mut Block_byref, src: *mut Block_byref)>

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 Block_byref)>

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