Struct Fields 

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

The named fields of a Datum::Constructed, in their wire order; JSON writes them as an object keyed by name in snake case, {"time_delay": 30, "low_limit": 10}.

Implementations

impl Fields

pub fn new(fields: Vec<(String, Datum)>) -> Self

Fields from (name, value) pairs, in order.

pub fn get(&self, name: &str) -> Option<&Datum>

The value of the field name.

pub fn iter(&self) -> impl Iterator<Item = (&str, &Datum)>

The fields in order, each its name and value.

pub fn len(&self) -> usize

How many fields there are.

pub fn is_empty(&self) -> bool

Whether there are none.
