A helper to help create dictionaries for you. It has the ability to insert values into the dictionary while maintaining the tags that need to be applied to the individual members

Implementations

impl TaggedDictBuilder

pub fn new(tag: impl Into<Tag>) -> TaggedDictBuilder

Create a new builder

pub fn build(
    tag: impl Into<Tag>,
    block: impl FnOnce(&mut TaggedDictBuilder)
) -> Value

Build the contents of the builder into a Value

pub fn with_capacity(tag: impl Into<Tag>, n: usize) -> TaggedDictBuilder

Create a new builder with a pre-defined capacity

pub fn insert_untagged(
    &mut self,
    key: impl Into<String>,
    value: impl Into<UntaggedValue>
)

Insert an untagged key/value pair into the dictionary, to later be tagged when built

pub fn insert_value(&mut self, key: impl Into<String>, value: impl Into<Value>)
