Struct PgNumeric

pub struct PgNumeric {
    pub n: Option<BigDecimal>,
}

A rust variant of the Postgres Numeric type. The full spectrum of Postgres’ Numeric value range is supported.

Represented as an Optional BigDecimal. None for ‘NaN’, Some(bigdecimal) for all other values.

Fields

n: Option<BigDecimal>

Implementations

impl PgNumeric

pub fn new(n: Option<BigDecimal>) -> Self

Construct a new PgNumeric value from an optional BigDecimal (None for NaN values).

pub fn is_nan(&self) -> bool

Returns true if this PgNumeric value represents a NaN value. Otherwise returns false.

Trait Implementations

impl Clone for PgNumeric

fn clone(&self) -> PgNumeric

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PgNumeric

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

Formats the value using the given formatter.

impl<'a> FromSql<'a> for PgNumeric

fn from_sql( _: &Type, raw: &'a [u8], ) -> Result<Self, Box<dyn Error + Sync + Send + 'static>>

Creates a new value of this type from a buffer of data of the specified Postgres Type in its binary format.

fn accepts(ty: &Type) -> bool

Determines if a value of this type can be created from the specified Postgres Type.

fn from_sql_null(ty: &Type) -> Result<Self, Box<dyn Error + Sync + Send>>

Creates a new value of this type from a NULL SQL value.

fn from_sql_nullable( ty: &Type, raw: Option<&'a [u8]>, ) -> Result<Self, Box<dyn Error + Sync + Send>>

A convenience function that delegates to from_sql and from_sql_null depending on the value of raw.

impl Ord for PgNumeric

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

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

fn partial_cmp(&self, other: &PgNumeric) -> 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 ToSql for PgNumeric

fn to_sql( &self, _: &Type, out: &mut BytesMut, ) -> Result<IsNull, Box<dyn Error + Sync + Send + 'static>>

Converts the value of self into the binary format of the specified Postgres Type, appending it to out.

fn accepts(ty: &Type) -> bool

Determines if a value of this type can be converted to the specified Postgres Type.

fn to_sql_checked( &self, ty: &Type, out: &mut BytesMut, ) -> Result<IsNull, Box<dyn Error + Sync + Send>>

An adaptor method used internally by Rust-Postgres.

fn encode_format(&self, _ty: &Type) -> Format

Specify the encode format
