Struct FiniteF64 

pub struct FiniteF64(/* private fields */);

Deterministic JSON-like attribute value for graph extensions.

The graph core keeps attributes typed enough to preserve booleans, numeric counters, nested ranges, and arrays without taking a JSON runtime dependency.

Implementations

impl FiniteF64

pub fn new(value: f64) -> Result<Self, String>

Creates a finite floating-point attribute value.

Errors

Returns an error for NaN and infinity, which are not valid JSON numbers.

pub const fn get(self) -> f64
