Struct Precision 

pub struct Precision(/* private fields */);

Precision for a decimal type (minimum 1 total digit)

Implementations

impl Precision

pub const MAX: Self

Maximum precision (255 - maximum u8 value)

pub const MIN: Self

Minimum precision (1)

pub fn new(precision: u8) -> Self

Create a new Precision value

Panics

Panics if precision is 0

pub fn try_new(precision: u8) -> Result<Self, Error>

Create a new Precision value, returning an error if invalid

pub fn value(self) -> u8

Get the precision value

Trait Implementations

impl Clone for Precision

fn clone(&self) -> Precision

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Precision

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Precision

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Precision

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

Formats the value using the given formatter.

impl From<Precision> for u8

fn from(precision: Precision) -> Self

Converts to this type from the input type.

impl From<u8> for Precision

fn from(value: u8) -> Self

Converts to this type from the input type.

impl Hash for Precision

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 Precision

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

impl PartialEq for Precision

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

impl PartialOrd for Precision

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

impl Serialize for Precision

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Precision

impl Eq for Precision
