Enum Number 

pub enum Number {
    I64(i64),
    U64(u64),
    F64(f64),
}

A number, kept in the widest lossless representation of its source.

Three variants rather than a single f64: JSON integers above i64::MAX (snowflake IDs, hashes) are real and must round-trip exactly, and f64 silently rounds them.

U64 is reserved for values that do not fit an i64; construct through Number::from_u64 to keep that canonical. Without it, derived PartialEq would make I64(1) != U64(1) and equality would depend on which parser produced the value.

Variants

I64(i64)

U64(u64)

F64(f64)

Implementations

impl Number

pub fn from_u64(u: u64) -> Self

Demotes to I64 when the value fits, so that every representable integer has exactly one representation.
