Struct Numeric

pub struct Numeric { /* private fields */ }

A fixed-width integer.

This type is used to pass fixed-width integers between the application code and the SQL engine.

Implementations

impl Numeric

pub fn new(val_scaled: i64, prec: usize) -> Option<Self>

Constructs a new fixed-width integer from a scaled value and precision.

Returns None if precision is greater or equal to 19.

Examples

A numeric value of 12.345 can be constructed using a scaled value of 12345 and a precision of 3:

let num = Numeric::new(12345, 3).unwrap();
assert_eq!(num.int_part(), 12);
assert_eq!(num.fract_part(), 345);

pub fn value_scaled(&self) -> i64

Returns the scaled value.

pub fn precision(&self) -> usize

Returns the precision.

pub fn int_part(&self) -> i64

Returns the integer part of the numeric value.

pub fn fract_part(&self) -> u64

Returns the fractional part of the numeric value.

pub fn destruct(self) -> (i64, usize)

Destructures the numeric value into the scaled value and the precision.

Trait Implementations
