Struct nu_protocol::value::dict::TaggedDictBuilder [−][src]
pub struct TaggedDictBuilder { /* fields omitted */ }
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
[src]
pub fn new(tag: impl Into<Tag>) -> TaggedDictBuilder
[src]
Create a new builder
pub fn build(
tag: impl Into<Tag>,
block: impl FnOnce(&mut TaggedDictBuilder)
) -> Value
[src]
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
[src]
Create a new builder with a pre-defined capacity
pub fn insert_untagged(
&mut self,
key: impl Into<String>,
value: impl Into<UntaggedValue>
)
[src]
&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>)
[src]
Insert a key/value pair into the dictionary
pub fn into_value(self) -> Value
[src]
Convert the dictionary into a tagged Value using the original tag
pub fn into_untagged_value(self) -> UntaggedValue
[src]
Convert the dictionary into an UntaggedValue
pub fn is_empty(&self) -> bool
[src]
Returns true if the dictionary is empty, false otherwise
pub fn contains_key(&self, key: &str) -> bool
[src]
Checks if given key exists
