Struct Decimal

pub struct Decimal {
    pub precision: i32,
    pub scale: i32,
    pub bit_width: i32,
}

Exact decimal value represented as an integer value in two’s complement. Currently 32-bit (4-byte), 64-bit (8-byte), 128-bit (16-byte) and 256-bit (32-byte) integers are used. The representation uses the endianness indicated in the Schema.

Generated from these locations:

• Table Decimal in the file Schema.fbs:229

Fields

precision: i32

Total number of decimal digits

scale: i32

Number of digits after the decimal point “.”

bit_width: i32

Number of bits per value. The accepted widths are 32, 64, 128 and 256. We use bitWidth for consistency with Int::bitWidth.

Implementations

impl Decimal

pub fn builder() -> DecimalBuilder<()>

Creates a DecimalBuilder for serializing an instance of this table.

pub fn create( builder: &mut Builder, field_precision: impl WriteAsDefault<i32, i32>, field_scale: impl WriteAsDefault<i32, i32>, field_bit_width: impl WriteAsDefault<i32, i32>, ) -> Offset<Self>

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

Formats the value using the given formatter.

impl Default for Decimal

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Decimal

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Decimal

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 Decimal

fn cmp(&self, other: &Decimal) -> 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 Decimal

fn eq(&self, other: &Decimal) -> 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 Decimal

fn partial_cmp(&self, other: &Decimal) -> 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 Decimal

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<'a> TryFrom<DecimalRef<'a>> for Decimal

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: DecimalRef<'a>) -> Result<Self>

Performs the conversion.

impl Eq for Decimal

impl StructuralPartialEq for Decimal

impl VectorWrite<Offset<Decimal>> for Decimal

Safety

The planus compiler generates implementations that initialize the bytes in write_values.

impl WriteAs<Offset<Decimal>> for Decimal

impl WriteAsOffset<Decimal> for Decimal

impl<T0: WriteAsDefault<i32, i32>, T1: WriteAsDefault<i32, i32>, T2: WriteAsDefault<i32, i32>> WriteAsOffset<Decimal> for DecimalBuilder<(T0, T1, T2)>
