Struct SeccompArg 

pub struct SeccompArg { /* private fields */ }

A condition on one argument of a syscall.

A condition names an argument by index (0 through 5, the six syscall registers), a width to compare, a comparison, and a reference value. It narrows which invocations of a listed syscall a SeccompRules rule matches — “ioctl only when its request equals TIOCGWINSZ,” “socket only when its domain equals AF_INET.”

The width-named constructors (eq_dword, eq_qword, and the rest) are the usual way to build one; they make the Dword/Qword choice explicit at the call site, since it has no safe default. new takes the parts directly.

Implementations

impl SeccompArg

pub fn new( index: u8, len: SeccompArgLen, compare: SeccompCompare, value: u64, ) -> SeccompArg

A condition from its parts: the argument index (0 through 5), the len to compare, the compare operation, and the reference value.

pub fn eq_dword(index: u8, value: u64) -> SeccompArg

The low 32 bits of argument index equal value.

pub fn eq_qword(index: u8, value: u64) -> SeccompArg

All 64 bits of argument index equal value.

pub fn ne_dword(index: u8, value: u64) -> SeccompArg

The low 32 bits of argument index do not equal value.

pub fn ne_qword(index: u8, value: u64) -> SeccompArg

All 64 bits of argument index do not equal value.

pub fn ge_dword(index: u8, value: u64) -> SeccompArg

The low 32 bits of argument index are greater than or equal to value.

pub fn ge_qword(index: u8, value: u64) -> SeccompArg

All 64 bits of argument index are greater than or equal to value.

pub fn gt_dword(index: u8, value: u64) -> SeccompArg

The low 32 bits of argument index are greater than value.

pub fn gt_qword(index: u8, value: u64) -> SeccompArg

All 64 bits of argument index are greater than value.

pub fn le_dword(index: u8, value: u64) -> SeccompArg

The low 32 bits of argument index are less than or equal to value.

pub fn le_qword(index: u8, value: u64) -> SeccompArg

All 64 bits of argument index are less than or equal to value.

pub fn lt_dword(index: u8, value: u64) -> SeccompArg

The low 32 bits of argument index are less than value.

pub fn lt_qword(index: u8, value: u64) -> SeccompArg

All 64 bits of argument index are less than value.

pub fn masked_eq_dword(index: u8, mask: u64, value: u64) -> SeccompArg

The low 32 bits of argument index, masked with mask, equal value masked with mask.

pub fn masked_eq_qword(index: u8, mask: u64, value: u64) -> SeccompArg

All 64 bits of argument index, masked with mask, equal value masked with mask.
