Struct Delta 

pub struct Delta { /* private fields */ }

An unsigned magnitude in ticks. Not tied to a profile: a count of ticks means the same thing under any profile that shares the tick (§5).

Implementations

impl Delta

pub fn zero() -> Self

Zero ticks.

pub fn one_tick() -> Self

One tick — the finest representable interval (G2, N10).

pub fn from_ticks(ticks: Ticks) -> Self

From a raw tick count.

pub fn from_u64(v: u64) -> Self

From a small tick count.

pub fn from_tier(tier: Tier, count: u64) -> Result<Self>

Whole multiples of a tier: count x 5^e.

pub fn ticks(&self) -> &Ticks

The raw tick count.

pub fn is_zero(&self) -> bool

Whether this is zero ticks.

pub fn checked_add(&self, other: &Delta) -> Result<Delta>

self + other, failing on domain exit (Rule O).

pub fn checked_sub(&self, other: &Delta) -> Result<Delta>

self - other, failing rather than wrapping (Rules Z, O).

pub fn mul_u64(&self, n: u64) -> Result<Delta>

self x n, failing on domain exit.

pub fn div_u64(&self, n: u64) -> Result<Delta>

Truncating self / n. Panics only if n is zero.

pub fn divmod(&self, divisor: &Delta) -> Result<(Delta, Delta)>

Quotient and remainder against another magnitude.

pub fn tier_of(&self) -> Option<Tier>

The largest tier no greater than self, or None if self is zero or smaller than one tick (which cannot happen — one tick is the floor).

pub fn in_tier(&self, tier: Tier) -> (Ticks, Ticks)

Whole count of a tier contained in self, and the remainder in ticks.

Trait Implementations

impl Clone for Delta

fn clone(&self) -> Delta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Delta

impl Debug for Delta

impl Ord for Delta

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

This method returns an Ordering between self and other.

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.
