Struct Scales 

pub struct Scales {
    by_kind: [Option<Scale>; 7],
}

A caller’s default scale per QuantityKind — what a book reports an unscaled measure in.

A value, not a setting: a book carries one, and two books with different scales report side by side in one process.

Fields

by_kind: [Option<Scale>; 7]

Implementations

impl Scales

pub fn new() -> Self

No defaults: every kind falls through to the measure’s own.

pub fn with(self, kind: QuantityKind, scale: Scale) -> Self

These defaults, with kind reported in scale.

pub fn get(&self, kind: QuantityKind) -> Option<Scale>

The default for kind, if one was stated.

fn slot(kind: QuantityKind) -> usize

Trait Implementations

impl Clone for Scales

fn clone(&self) -> Scales

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Scales

impl Debug for Scales

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

Formats the value using the given formatter.

impl Default for Scales

fn default() -> Scales

Returns the “default value” for a type.

impl Eq for Scales

impl Hash for Scales

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 PartialEq for Scales

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