Enum libseccomp::ScmpCompareOp

#[non_exhaustive]
pub enum ScmpCompareOp {
    NotEqual,
    Less,
    LessOrEqual,
    Equal,
    GreaterEqual,
    Greater,
    MaskedEqual(u64),
}

Represents a comparison operator which can be used in a filter rule.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NotEqual

Not equal

Less

Less than

LessOrEqual

Less than or equal

Equal

Equal

GreaterEqual

Greater than or equal

Greater

Greater than

MaskedEqual(u64)

Tuple Fields

0: u64

mask

Masked equality

This works like Equal with the exception that the syscall argument is masked with mask via an bitwise AND (i.e. you can check specific bits in the argument).

Trait Implementations

impl Clone for ScmpCompareOp

fn clone(&self) -> ScmpCompareOp

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ScmpCompareOp

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromStr for ScmpCompareOp

fn from_str(cmp_op: &str) -> Result<Self, SeccompError>

Converts string seccomp comparison operator to ScmpCompareOp.

Arguments

• cmp_op - A string comparison operator, e.g. SCMP_CMP_*.

See the seccomp_rule_add(3) man page for details on valid comparison operator values.

Errors

If an invalid comparison operator is specified, an error will be returned.

type Err = SeccompError

The associated error which can be returned from parsing.

impl Hash for ScmpCompareOp

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,

Feeds a slice of this type into the given Hasher.

impl PartialEq<ScmpCompareOp> for ScmpCompareOp

fn eq(&self, other: &ScmpCompareOp) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
