Implementations

impl CapabilitiesSecureBits

pub const NO_ROOT: CapabilitiesSecureBits

If this bit is set, then the kernel does not grant capabilities when a set-user-ID-root program is executed, or when a process with an effective or real UID of 0 calls execve.

pub const NO_ROOT_LOCKED: CapabilitiesSecureBits

Set NO_ROOT irreversibly.

pub const NO_SETUID_FIXUP: CapabilitiesSecureBits

Setting this flag stops the kernel from adjusting the process’ permitted, effective, and ambient capability sets when the thread’s effective and filesystem UIDs are switched between zero and nonzero values.

pub const NO_SETUID_FIXUP_LOCKED: CapabilitiesSecureBits

Set NO_SETUID_FIXUP irreversibly.

pub const KEEP_CAPS: CapabilitiesSecureBits

Setting this flag allows a thread that has one or more 0 UIDs to retain capabilities in its permitted set when it switches all of its UIDs to nonzero values.

pub const KEEP_CAPS_LOCKED: CapabilitiesSecureBits

Set KEEP_CAPS irreversibly.

pub const NO_CAP_AMBIENT_RAISE: CapabilitiesSecureBits

Setting this flag disallows raising ambient capabilities via the prctl’s PR_CAP_AMBIENT_RAISE operation.

pub const NO_CAP_AMBIENT_RAISE_LOCKED: CapabilitiesSecureBits

Set NO_CAP_AMBIENT_RAISE irreversibly.

Convert from a bits value.

This method will return None if any unknown bits are set.

Convert from a bits value exactly.

pub fn from_name(name: &str) -> Option<CapabilitiesSecureBits>

Get a flags value with the bits of a flag with the given name set.

This method will return None if name is empty or doesn’t correspond to any named flag.

Whether all bits in this flags value are unset.

pub const fn is_all(&self) -> bool

Whether all known bits in this flags value are set.

pub fn insert(&mut self, other: CapabilitiesSecureBits)

The bitwise or (|) of the bits in two flags values.

pub fn remove(&mut self, other: CapabilitiesSecureBits)

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. remove won’t truncate other, but the ! operator will.

pub fn toggle(&mut self, other: CapabilitiesSecureBits)

The bitwise exclusive-or (^) of the bits in two flags values.

pub fn set(&mut self, other: CapabilitiesSecureBits, value: bool)

Call insert when value is true or remove when value is false.

The bitwise or (|) of the bits in two flags values.

pub const fn difference( self, other: CapabilitiesSecureBits, ) -> CapabilitiesSecureBits

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. difference won’t truncate other, but the ! operator will.

pub const fn symmetric_difference( self, other: CapabilitiesSecureBits, ) -> CapabilitiesSecureBits

The bitwise exclusive-or (^) of the bits in two flags values.

pub const fn complement(self) -> CapabilitiesSecureBits

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl CapabilitiesSecureBits

pub const fn iter(&self) -> Iter<CapabilitiesSecureBits>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

pub const fn iter_names(&self) -> IterNames<CapabilitiesSecureBits>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
