Struct InterfaceFlags 

pub struct InterfaceFlags(/* private fields */);

Available on crate feature net only.

Status and capability flags of a local network Interface.

Mapped from IFF_* on unix platforms and from the adapter’s operational status and type on windows; per-flag notes below call out where the platforms differ.

String format

InterfaceFlags round-trips (Display/FromStr/serde) through a comma-separated list of kebab-case flag names, e.g. "up,running". Parsing is allocation-free and lenient: ASCII case-insensitive, _ equals -, and | is also accepted as separator. An empty string parses as the empty set.

Implementations

impl InterfaceFlags

pub const UP: InterfaceFlags

Interface is administratively up.

On windows this is set together with InterfaceFlags::RUNNING when the adapter’s operational status is up; the two states are not reported separately there.

pub const RUNNING: InterfaceFlags

Interface is operationally running (e.g. carrier present).

pub const LOOPBACK: InterfaceFlags

Loopback interface.

pub const POINT_TO_POINT: InterfaceFlags

Point-to-point link (tunnels, PPP).

pub const BROADCAST: InterfaceFlags

Broadcast-capable link. Never set on windows.

pub const MULTICAST: InterfaceFlags

Multicast-capable link.

impl InterfaceFlags

pub const fn empty() -> InterfaceFlags

Get a flags value with all bits unset.

pub const fn all() -> InterfaceFlags

Get a flags value with all known bits set.

pub const fn bits(&self) -> u8

Get the underlying bits value.

The returned value is exactly the bits set in this flags value.

pub const fn from_bits(bits: u8) -> Option<InterfaceFlags>

Convert from a bits value.

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

pub const fn from_bits_truncate(bits: u8) -> InterfaceFlags

Convert from a bits value, unsetting any unknown bits.

pub const fn from_bits_retain(bits: u8) -> InterfaceFlags

Convert from a bits value exactly.

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

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.

pub const fn is_empty(&self) -> bool

Whether all bits in self are unset.

pub const fn is_all(&self) -> bool

Whether all known bits in this flags value are set.

pub const fn intersects(&self, other: InterfaceFlags) -> bool

Whether any set bits in other are also set in self.

pub const fn contains(&self, other: InterfaceFlags) -> bool

Whether all set bits in other are also set in self.

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

The bitwise or (|) of the bits in self and other.

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

The intersection of self with the complement of other (&!).

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: InterfaceFlags)

The bitwise exclusive-or (^) of the bits in self and other.

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

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

pub const fn intersection(self, other: InterfaceFlags) -> InterfaceFlags

The bitwise and (&) of the bits in self and other.

pub const fn union(self, other: InterfaceFlags) -> InterfaceFlags

The bitwise or (|) of the bits in self and other.

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

The intersection of self with the complement of other (&!).

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: InterfaceFlags) -> InterfaceFlags

The bitwise exclusive-or (^) of the bits in self and other.

pub const fn complement(self) -> InterfaceFlags

The bitwise negation (!) of the bits in self, truncating the result.

impl InterfaceFlags

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

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<InterfaceFlags>

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.
