Struct Number 

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

A JSON number, in the lexical form the document carried.

FHIR forbids reading a decimal through a binary float: “Do not use an IEEE type floating point type, instead use something that works like a true decimal” (https://hl7.org/fhir/R4B/datatypes.html#decimal), so the number keeps its text and the codec never rounds it.

Implementations

impl Number

pub fn as_str(&self) -> &str

The number as it was written.

pub fn as_i64(&self) -> Option<i64>

The number as an i64, None when it is no whole number in range.

pub fn as_u64(&self) -> Option<u64>

The number as a u64, None when it is no whole number in range.
