Struct proof_of_sql_parser::intermediate_decimal::IntermediateDecimal

pub struct IntermediateDecimal { /* private fields */ }

An intermediate placeholder for a decimal

Implementations

impl IntermediateDecimal

pub fn value(&self) -> BigDecimal

Get the integer part of the fixed-point representation of this intermediate decimal.

pub fn precision(&self) -> u8

Get the precision of the fixed-point representation of this intermediate decimal.

pub fn scale(&self) -> i8

Get the scale of the fixed-point representation of this intermediate decimal.

pub fn try_into_bigint_with_precision_and_scale( &self, precision: u8, scale: i8, ) -> Result<BigInt, IntermediateDecimalError>

Attempts to convert the decimal to BigInt while adjusting it to the specified precision and scale. Returns an error if the conversion cannot be performed due to precision or scale constraints.

Trait Implementations

impl Clone for IntermediateDecimal

fn clone(&self) -> IntermediateDecimal

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IntermediateDecimal

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for IntermediateDecimal

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for IntermediateDecimal

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

Formats the value using the given formatter.

impl From<IntermediateDecimal> for Literal

fn from(val: IntermediateDecimal) -> Self

Converts to this type from the input type.

impl From<i128> for IntermediateDecimal

fn from(value: i128) -> Self

Converts to this type from the input type.

impl From<i64> for IntermediateDecimal

fn from(value: i64) -> Self

Converts to this type from the input type.

impl FromStr for IntermediateDecimal

type Err = IntermediateDecimalError

The associated error which can be returned from parsing.

fn from_str(decimal_string: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for IntermediateDecimal

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&str> for IntermediateDecimal

type Error = IntermediateDecimalError

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<IntermediateDecimal> for i128

type Error = IntermediateDecimalError

The type returned in the event of a conversion error.

fn try_from(decimal: IntermediateDecimal) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<IntermediateDecimal> for i64

type Error = IntermediateDecimalError

The type returned in the event of a conversion error.

fn try_from(decimal: IntermediateDecimal) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<String> for IntermediateDecimal

type Error = IntermediateDecimalError

The type returned in the event of a conversion error.

fn try_from(s: String) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for IntermediateDecimal
