Enum IpStack 

pub enum IpStack {
    None,
    V4Only,
    V6Only,
    DualStack,
}

The IP-stack capability currently available to the host.

This reflects which IP protocol versions the host has usable addresses / routes for, as reported by the underlying netwatch interface state (have_v4 / have_v6). The semantics are identical across platforms: it describes local stack availability, not per-protocol Internet reachability.

Variants

None

Neither IPv4 nor IPv6 is available.

V4Only

Only IPv4 is available.

V6Only

Only IPv6 is available.

DualStack

Both IPv4 and IPv6 are available.

Implementations

impl IpStack

pub const fn name(&self) -> &'static str

The variant name as a static string (e.g. "DualStack").

Used both by the fmt::Display implementation and as a stable, human-readable label when forwarding the value to logging.

pub const fn has_ipv4(&self) -> bool

Whether IPv4 is available (true for IpStack::V4Only and IpStack::DualStack).

pub const fn has_ipv6(&self) -> bool

Whether IPv6 is available (true for IpStack::V6Only and IpStack::DualStack).

pub const fn is_dual_stack(&self) -> bool

Whether both IPv4 and IPv6 are available.

Trait Implementations

impl Clone for IpStack

fn clone(&self) -> IpStack

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for IpStack

impl Debug for IpStack

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

Formats the value using the given formatter.

impl Default for IpStack

fn default() -> IpStack

Returns the “default value” for a type.

impl Display for IpStack

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

Renders the variant name, so to_string() yields e.g. "DualStack" rather than a structural form.

impl Eq for IpStack

impl PartialEq for IpStack

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

Equality operator ==.

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

Inequality operator !=.
