Enum CounterPolicy 

pub enum CounterPolicy {
    Rollover {
        bits: u8,
        step: u32,
    },
    None,
}

How counters should evolve across a session.

Variants

Rollover

Monotonic with rollover of bits width and fixed step (usually 1).

Fields

bits: u8

step: u32

None

No policy (accept any counter).

Implementations

impl CounterPolicy

pub fn next(self, prev: Option<u32>) -> u32

Compute the next counter to use for transmission given the previous one.

pub fn ok(self, prev: Option<u32>, next: u32) -> bool

Validate whether next is the correct successor of prev.

Trait Implementations

impl Clone for CounterPolicy

fn clone(&self) -> CounterPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CounterPolicy

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

Formats the value using the given formatter.

impl PartialEq for CounterPolicy

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