#[repr(transparent)]
pub struct Fork(u32);

Flags to control behavior of ProcMgr::fork().

Tuple Fields

0: u32

Implementations

impl Fork

pub const CopyFd: Mask<Self, bool>

Duplicate file descriptor table to the child instead of sharing it with the parent. Cannot used together with [Self::clear_fd()].

This has the same value as RFFDG.

pub const CreateProcess: Mask<Self, bool>

Create a child process.

This has the same value as RFPROC.

pub const ClearFd: Mask<Self, bool>

Create an empty file descriptor table for the child. Cannot used together with [Self::copy_fd()].

This has the same value as RFCFDG.

pub const CustomSignal: Mask<Self, bool>

Enable [Self::parent_signal()].

This has the same value as RFTSIGZMB.

pub const ParentSignal: Mask<Self, Signal>

Use this signal instead of SIGCHLD to notify the parent. Requires [Self::custom_signal()] to be enabled.

This has the same value produced by RFTSIGNUM macro.

pub const fn zeroed() -> Self

Returns a new set with all bits of the backed-storage set to zero.

pub fn has_any(self, rhs: impl Into<Self>) -> bool

Returns true if this set contains any flags in the rhs set.

This performs the & operation on the underlying value and check if the results is non-zero.

pub const fn has_all(self, rhs: Self) -> bool

Returns true if this set contains all flags in the rhs set.

This performs the & operation on the underlying value and check if the results is equal to rhs.

pub fn get<T>(self, m: Mask<Self, T>) -> T

where T: FromRaw<u32>,

Panics

If m is not valid for T.

Trait Implementations

impl BitAnd for Fork

type Output = Fork

The resulting type after applying the & operator.

fn bitand(self, rhs: Self) -> Self::Output

Performs the & operation.

impl BitOr<Mask<Fork, bool>> for Fork

type Output = Fork

The resulting type after applying the | operator.

fn bitor(self, rhs: Mask<Self, bool>) -> Self::Output

Performs the | operation.

impl BitOrAssign<Mask<Fork, bool>> for Fork

fn bitor_assign(&mut self, rhs: Mask<Self, bool>)

Performs the |= operation.

impl BitOrAssign for Fork

fn bitor_assign(&mut self, rhs: Self)

Performs the |= operation.

impl Clone for Fork

fn clone(&self) -> Fork

Returns a copy of the value.

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

Performs copy-assignment from source.

impl From<Fork> for u32

fn from(value: Fork) -> Self

Converts to this type from the input type.

impl From<Mask<Fork, bool>> for Fork

fn from(value: Mask<Self, bool>) -> Self

Converts to this type from the input type.

impl From<u32> for Fork

fn from(value: u32) -> Self

Converts to this type from the input type.

impl PartialEq<Mask<Fork, bool>> for Fork

fn eq(&self, other: &Mask<Self, bool>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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