Struct UserRegisters 

#[repr(C)]
pub struct UserRegisters {
    pub regs: GeneralRegisters,
    pub vector: u64,
    pub error_code: u64,
    pub rip: u64,
    pub cs: u64,
    pub rflags: u64,
    pub rsp: u64,
    pub ss: u64,
}

Saved registers when a trap (interrupt or exception) occurs.

Fields

regs: GeneralRegisters

Software-saved general registers, shared with virtualization entries.

vector: u64

Trap vector supplied by the assembly entry.

error_code: u64

Hardware error code, or zero for vectors without one.

rip: u64

Interrupted instruction pointer.

cs: u64

Interrupted code segment selector.

rflags: u64

Interrupted flags register.

rsp: u64

Interrupted stack pointer, saved even for a same-privilege entry.

ss: u64

Interrupted stack segment selector.
