Struct Decimal

pub struct Decimal { /* private fields */ }

Provides arbitrary-precision floating point decimal.

Implementations

impl Decimal

pub fn of<B: Base>(source: B, scale: u8) -> Decimal

Method of creating a Decimal.

pub fn internal<I: InternalResult>(&self) -> I

Get the internal representation of decimal as i32 or i64.

example:

    .and_then(move |c| c.query("SELECT toDecimal32(2, 4) AS x").fetch_all())
    .and_then(move |(_, block)| {
        let x: Decimal = block.get(0, "x")?;
        let actual: i32 = x.internal();
        assert_eq!(20000, actual);
    })

pub fn scale(&self) -> usize

Determines how many decimal digits fraction can have.

Trait Implementations

impl Clone for Decimal

fn clone(&self) -> Decimal

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Decimal

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

Formats the value using the given formatter.

impl Default for Decimal

fn default() -> Self

Returns the “default value” for a type.

impl Display for Decimal

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

Formats the value using the given formatter.

impl From<Decimal> for Value

fn from(v: Decimal) -> Value

Converts to this type from the input type.

impl From<Decimal> for f32

fn from(value: Decimal) -> Self

Converts to this type from the input type.

impl From<Decimal> for f64

fn from(value: Decimal) -> Self

Converts to this type from the input type.

impl<'a> FromSql<'a> for Decimal

fn from_sql(value: ValueRef<'a>) -> Result<Self, Error>

impl<'a> Iterable<'a, Simple> for Decimal

type Iter = DecimalIterator<'a>

fn iter(column: &'a Column<Simple>, column_type: SqlType) -> Result<Self::Iter>

impl PartialEq for Decimal

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