Struct capctl::caps::FullCapState

#[non_exhaustive]pub struct FullCapState {
    pub permitted: CapSet,
    pub effective: CapSet,
    pub inheritable: CapSet,
    pub ambient: CapSet,
    pub bounding: CapSet,
    pub no_new_privs: bool,
}

Represents the "full" capability state of a thread (i.e. the contents of all 5 capability sets and some additional information).

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

permitted: CapSet

effective: CapSet

inheritable: CapSet

ambient: CapSet

bounding: CapSet

no_new_privs: bool

Implementations

impl FullCapState

pub fn empty() -> Self

Construct an empty FullCapState object.

pub fn get_current() -> Result<Self>

Get the full capability state of the current thread.

This is equivalent to FullCapState::get_for_pid(0). However, this method uses the kernel APIs to retrieve information instead of examining files in /proc.

pub fn get_for_pid(pid: pid_t) -> Result<Self>

Get the full capability state of the process (or thread) with the given PID (or TID) by examining special files in /proc.

If pid is 0, this method gets the capability state of the current thread.

Trait Implementations

impl Clone for FullCapState

fn clone(&self) -> FullCapState

Returns a copy of the value.
