rustc_middle::mir::interpret::allocation::init_mask

Struct InitCopy

source 
pub struct InitCopy {
    initial: bool,
    ranges: SmallVec<[u64; 1]>,
}
Expand description

Run-length encoding of the uninit mask. Used to copy parts of a mask multiple times to another allocation.

Fields§

§initial: bool

Whether the first range is initialized.

§ranges: SmallVec<[u64; 1]>

The lengths of ranges that are run-length encoded. The initialization state of the ranges alternate starting with initial.
