Struct LeaseTime

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

The time, in seconds, before a lease expires. A lower value will increase dhcp traffic between client and server. A higher value will increase the chances that all ip addresses are assigned. The maximum value (4,294,967,295) is reserved to represent Infinity.

Lease time must be at least a minute because:

1. The server must subtract some time to account for drift.
2. The default value for T1 (renewal time) is half of the lease_time.

Implementations

impl LeaseTime

pub fn new(lease_time: u32) -> Result<Self>

Construct a valid lease_time field.

pub fn as_server(&self) -> u32

The actual lease_time, not adjusted for drift.

pub fn as_client(&self) -> u32

The lease_time, with a small amount subtracted to adjust for drift

Trait Implementations

impl Debug for LeaseTime

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LeaseTime

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for LeaseTime

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

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

const 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 Serialize for LeaseTime

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
