# 1.27.0[−][src]Function core::arch::x86_64::_xrstors64

    pub unsafe fn _xrstors64(mem_addr: *const u8, rs_mask: u64)

This is supported on x86-64 and target feature `xsave,xsaves` only.

Perform a full or partial restore of the enabled processor states using the state information stored in memory at `mem_addr`.

`xrstors` differs from `xrstor` in that it can restore state components corresponding to bits set in the `IA32_XSS` `MSR`; `xrstors` cannot restore from an `xsave` area in which the extended region is in the standard form. State is restored based on bits `[62:0]` in `rs_mask`, `XCR0`, and `mem_addr.HEADER.XSTATE_BV`. `mem_addr` must be aligned on a 64-byte boundary.

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
