pub enum Number {
    PosInt(u64),
    NegInt(i64),
    Float(f64),
}
Expand description

A number type that implements Javascript / JSON semantics, modeled on serde_json: https://docs.serde.rs/src/serde_json/number.rs.html#20-22

Variants§

§

PosInt(u64)

Unsigned 64-bit integer value.

§

NegInt(i64)

Signed 64-bit integer value. The wrapped value is always negative.

§

Float(f64)

64-bit floating-point value.

Implementations§

source§

impl Number

source

pub fn to_f64_lossy(self) -> f64

Converts to an f64 lossily. Use Number::try_from to make the conversion only if it is not lossy.

source

pub fn to_f32_lossy(self) -> f32

Converts to an f32 lossily. Use Number::try_from to make the conversion only if it is not lossy.
