Struct Decimal128Value 

pub struct Decimal128Value { /* private fields */ }

Decimal128 Value Wrapper

Wraps the dec::Decimal128 type to provide integration with the Linkrs type system.

Example

use linkrs_core::value::decimal128::Decimal128Value;

let d1 = "123.456".parse::<Decimal128Value>().expect("parse failed");
let d2 = "789.012".parse::<Decimal128Value>().expect("parse failed");
let sum = &d1 + &d2;
assert_eq!(sum.to_string(), "912.468");
