Enum NonZeroNdpLifetime

pub enum NonZeroNdpLifetime {
    Finite(NonZeroDuration),
    Infinite,
}

A non-zero lifetime conveyed through NDP.

Variants

Finite(NonZeroDuration)

A finite lifetime greater than zero.

Note that the finite lifetime is not statically guaranteed to be less than the infinite value representation of a field. E.g. for Prefix Information option lifetime 32-bit fields, infinity is represented as all 1s but it is possible for this variant to hold a value representing X seconds where X is >= 2^32.

Infinite

An infinite lifetime.

Implementations

impl NonZeroNdpLifetime

pub fn from_u32_with_infinite(lifetime: u32) -> Option<NonZeroNdpLifetime>

Returns a Some(NonZeroNdpLifetime) if the passed lifetime is non-zero; otherwise None.

pub fn min_finite_duration(self, other: NonZeroDuration) -> NonZeroDuration

Returns the minimum finite duration.

Trait Implementations

impl Clone for NonZeroNdpLifetime

fn clone(&self) -> NonZeroNdpLifetime

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NonZeroNdpLifetime

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

Formats the value using the given formatter.

impl Ord for NonZeroNdpLifetime

fn cmp(&self, other: &NonZeroNdpLifetime) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for NonZeroNdpLifetime

fn eq(&self, other: &NonZeroNdpLifetime) -> 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.

impl PartialOrd for NonZeroNdpLifetime

fn partial_cmp(&self, other: &NonZeroNdpLifetime) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
