Struct U64String 

pub struct U64String(/* private fields */);

A u64 that serializes as a JSON string.

JSON integer parsing in the browser (JavaScript Number) is limited to 2⁵³ bits. x402 wraps u64-sized fields in strings to guarantee exact precision across runtimes.

Examples

use r402_core::wire::U64String;

let value = U64String::from(42_u64);
assert_eq!(value.inner(), 42);
assert_eq!(serde_json::to_string(&value).unwrap(), r#""42""#);
let parsed: U64String = serde_json::from_str(r#""42""#).unwrap();
assert_eq!(parsed.inner(), 42);
