Struct Measurement 

pub struct Measurement<U> { /* private fields */ }

Equality compares the unit too: convert before comparing across units.

Implementations

impl<U: Unit> Measurement<U>

pub fn try_new(thousandths: i64, unit: U) -> Result<Self>

pub fn parse(quantity: &str, unit: U) -> Result<Self>

pub fn thousandths(self) -> i64

pub fn unit(self) -> U

pub fn quantity(self) -> String

pub fn convert(self, unit: U) -> Result<Self>

Trait Implementations

impl<U: Unit> Cast for Measurement<U>

Whole thousandths survive the float column exactly. Unordered: the quantity alone would put 500 grams after 2 kilograms.

const COLUMNS: &'static [ColumnSpec]

fn encode(&self, out: &mut Vec<SqlValue>)

fn decode(row: &mut dyn ColumnReader) -> Result<Self>

const NULLABLE: bool = false

const SENSITIVE: bool = false

A field holding it is never filtered, sorted, listed or searched, as #[sensitive] ones.

const MOVES: Option<fn(&Self) -> Option<&'static Targets>> = None

Set for a value moving between listed states; a save of any other value skips the check.

const HOLDS_STATES: bool = _

Set when a state anywhere in the value is checked on save, as a field’s of several.

fn refuse_unlisted_move( field: &str, stored: &Self, current: &Self, ) -> Result<(), Error>

impl<U: Clone> Clone for Measurement<U>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<U: Copy> Copy for Measurement<U>

impl<U: Debug> Debug for Measurement<U>

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

Formats the value using the given formatter.

impl<'de, U: Unit> Deserialize<'de> for Measurement<U>

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl<U: Eq> Eq for Measurement<U>

impl<U: Unit> Fields for Measurement<U>

fn name(&self, index: usize) -> Option<&str>

fn get(&self, name: &str) -> Option<Shown<'_>>

fn names(&self) -> Box<dyn Iterator<Item = &str> + '_>

Overridden where name(index) walks from the start, so a walk over all fields stays linear.

impl<U: Unit> Filter for Measurement<U>

Available on crate feature measure only.

const OPERATORS: &'static [Operator] = EXACT

impl<U: Unit> Fixture for Measurement<U>

fn fixture(seed: &mut Seed) -> Self

impl<U: Hash> Hash for Measurement<U>

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<U: Unit> LogFields for Measurement<U>

Available on crate feature measure only.

fn log_fields(&self, field: &mut dyn FnMut(Option<&'static str>, LogValue<'_>))

None as the member name logs the value whole.

impl<U: PartialEq> PartialEq for Measurement<U>

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

Equality operator ==.

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

Inequality operator !=.

impl<U: Unit> Present for Measurement<U>

const INPUT: Input

const SEARCH: Search = crate::Search::Number

fn csv(&self) -> String

fn write_localized(&self, out: &mut String, conventions: &dyn Conventions)

impl<U: Unit> Serialize for Measurement<U>

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl<U: Unit> Show for Measurement<U>

fn show(&self) -> Shown<'_>

impl<U: PartialEq> StructuralPartialEq for Measurement<U>
