Struct Map 

pub struct Map {
    pub a: i128,
    pub b: i128,
    pub d: i128,
    pub between: Between,
}

Reader sample n reads source sample (a*n + b)/d, d > 0: exactly, or rounded down or to the nearest, ties to even. An exact map is whole, d = 1; nothing reads between samples.

Fields

a: i128

b: i128

d: i128

between: Between

Implementations

impl Map

pub const fn shift(b: i64) -> Map

pub const fn whole(a: i128, b: i64) -> Map

Reader sample n reads source sample a*n + b.

pub fn new(a: i128, b: i128, d: i128) -> Option<Map>

Lowest terms; None where a sample lands between two, or past what a map holds.

pub fn rounded(a: i128, b: i128, d: i128, between: Between) -> Option<Map>

A rounding every sample takes alike is folded into an exact map.

pub fn at(self, n: i64) -> i64

pub fn ahead(self) -> bool

pub fn lead(self) -> i64

pub fn least(self) -> i64

pub fn image(self, over: Extent) -> Extent

pub fn preimage(self, into: Extent) -> Extent

The reader samples whose reading lands in into. Rounding to even reads at most one below rounding half up.

Trait Implementations

impl Clone for Map

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Map

impl Debug for Map

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

Formats the value using the given formatter.

impl Eq for Map

impl Hash for Map

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Map

fn cmp(&self, other: &Self) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Map

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Map

fn partial_cmp(&self, other: &Self) -> 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.
