pub const EXACT_JSON_INTEGER: i128 = _ /* 9_007_199_254_740_992i128 */;Expand description
The largest integer a JSON number carries without loss.
A JSON number is a double, so 9007199254740993 does not survive the
round trip through one. tests/interop-corpus/README.md states the
rule the corpus is written to — “a 64-bit integer is a string”
— and this is where it is enforced rather than only documented.
