Struct Numeric 

pub struct Numeric(pub String);

NUMERIC/DECIMAL type (stored as string for precision)

Tuple Fields

0: String

Implementations

impl Numeric

pub fn new(s: impl Into<String>) -> Self

Create from string representation

pub fn to_f64(&self) -> Result<f64, ParseFloatError>

Parse as f64 (may lose precision for very large numbers)

pub fn to_i64(&self) -> Result<i64, ParseIntError>

Parse as i64 (truncates decimal part)

pub fn to_i64_exact(&self) -> Result<i64, ParseIntError>

Parse as i64 only when the numeric value has no non-zero decimal part.

pub fn is_integral(&self) -> bool

Whether the decimal representation has no non-zero fractional digits.

pub fn as_str(&self) -> &str

Get the string representation

Trait Implementations

impl Clone for Numeric

fn clone(&self) -> Numeric

Returns a duplicate 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

Formats the value using the given formatter.

impl FromPg for Numeric

fn from_pg(bytes: &[u8], oid_val: u32, format: i16) -> Result<Self, TypeError>

Convert from PostgreSQL wire format.

impl PartialEq for Numeric

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

fn to_pg(&self) -> (Vec<u8>, u32, i16)

Convert to PostgreSQL wire format. Returns (bytes, oid, format_code)
