Enum bonsaidb::core::keyvalue::Numeric

pub enum Numeric {
    Integer(i64),
    UnsignedInteger(u64),
    Float(f64),
}

A numerical value.

Variants

Integer(i64)

A 64-bit signed integer.

UnsignedInteger(u64)

A 64-bit unsigned integer.

Float(f64)

A 64-bit floating point number.

Implementations

impl Numeric

pub fn validate(self) -> Result<Numeric, Error>

Ensures this value contains a valid value.

Errors

Error::NotANumber is returned if this contains a NaN floating point value.

pub fn as_i64(&self) -> Option<i64>

Returns this numeric as an i64. If this conversion cannot be done without losing precision or overflowing, None will be returned.

pub fn as_i64_lossy(&self, saturating: bool) -> i64

Returns this numeric as an i64, allowing for precision to be lost if the type was not an i64 originally. If saturating is true, the conversion will not allow overflows.

pub fn as_u64(&self) -> Option<u64>

Returns this numeric as an u64. If this conversion cannot be done without losing precision or overflowing, None will be returned.

pub fn as_u64_lossy(&self, saturating: bool) -> u64

Returns this numeric as an u64, allowing for precision to be lost if the type was not an i64 originally. If saturating is true, the conversion will not allow overflows.

pub const fn as_f64(&self) -> Option<f64>

Returns this numeric as an f64. If this conversion cannot be done without losing precision, None will be returned.

pub const fn as_f64_lossy(&self) -> f64

Returns this numeric as an f64, allowing for precision to be lost if the type was not an f64 originally.

Trait Implementations

impl Clone for Numeric

fn clone(&self) -> Numeric

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Numeric

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Numeric

fn deserialize<__D>( __deserializer: __D ) -> Result<Numeric, <__D as Deserializer<'de>>::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<f64> for Numeric

fn from(value: f64) -> Numeric

Converts to this type from the input type.

impl From<i64> for Numeric

fn from(value: i64) -> Numeric

Converts to this type from the input type.

impl From<u64> for Numeric

fn from(value: u64) -> Numeric

Converts to this type from the input type.

impl PartialEq<Numeric> for Numeric

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Numeric

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

Serialize this value into the given Serde serializer.
