Struct LosslessFloat 

pub struct LosslessFloat(/* private fields */);

Available on crate feature lossless-float only.

A float that rejects values outside f64’s precise representation range.

The round-trip invariant is: if a value loses precision when converted to f64 and back, construction fails. This catches values like 1e308 * 2 (infinity) or subnormals that cannot be faithfully represented.

The check runs on the decoded f64 value, after the parser’s own scalar resolution — it guards the value, not the source lexeme.

Examples

use noyalib::lossless_float::LosslessFloat;

let f: LosslessFloat = noyalib::from_str("3.14159").unwrap();
assert!((f.get() - 3.14159).abs() < 1e-10);

// Infinity is rejected.
let result: Result<LosslessFloat, _> = noyalib::from_str(".inf");
assert!(result.is_err());

Implementations

impl LosslessFloat

pub fn get(self) -> f64

Returns the inner f64 value.

Examples

use noyalib::lossless_float::LosslessFloat;
let f = LosslessFloat::try_from(2.5).unwrap();
assert_eq!(f.get(), 2.5);
