Implementations

impl SlotRange

pub fn n(value: u8) -> Option<Self>

impl SlotRange

pub const LEASE_PERIODS_PER_SLOT: usize = 8usize

pub const SLOT_RANGE_COUNT: usize = 36usize

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

Return true if two SlotRange intersect in their lease periods.

pub fn as_pair(&self) -> (u8, u8)

Return a tuple representation of the SlotRange.

Example:SlotRange::OneTwo.as_pair() == (1, 2)

pub fn len(&self) -> usize

Return the length of occupying a SlotRange.

Example:SlotRange::OneTwo.len() == 2

pub fn new_bounded<Index: Add<Output = Index> + CheckedSub + Copy + Ord + From<u32> + TryInto<u32>>(
    current: Index,
    first: Index,
    last: Index
) -> Result<Self, &'static str>

Construct a SlotRange from the current lease period, the first lease period of the range, and the last lease period of the range.

For example: SlotRange::new_bounded(1, 2, 3) == SlotRange::OneTwo.

Trait Implementations

impl Clone for SlotRange

fn clone(&self) -> SlotRange

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SlotRange

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

Formats the value using the given formatter.

impl Decode for SlotRange

fn decode<__CodecInputEdqy: Input>(
    __codec_input_edqy: &mut __CodecInputEdqy
) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn skip<I>(input: &mut I) -> Result<(), Error>where
    I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Encode for SlotRange

fn encode_to<__CodecOutputEdqy: Output + ?Sized>(
    &self,
    __codec_dest_edqy: &mut __CodecOutputEdqy
)

Convert self to a slice and append it to the destination.

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode(&self) -> Vec<u8, Global>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> Rwhere
    F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl Ord for SlotRange

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<SlotRange> for SlotRange

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<SlotRange> for SlotRange

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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