Struct Dict

pub struct Dict<'k, 'v> { /* private fields */ }

A helper type to wrap dictionaries in a Value.

API is provided to convert from, and to a HashMap.

Implementations

impl<'k, 'v> Dict<'k, 'v>

pub fn new(key_signature: &Signature, value_signature: &Signature) -> Self

Create a new empty Dict, given the signature of the keys and values.

pub fn append<'kv: 'k, 'vv: 'v>( &mut self, key: Value<'kv>, value: Value<'vv>, ) -> Result<(), Error>

Append key and value as a new entry.

Errors

• if key.value_signature() doesn’t match the key signature self was created for.
• if value.value_signature() doesn’t match the value signature self was created for.

where K: Basic + Into<Value<'k>> + Ord, V: Into<Value<'v>> + DynamicType,

Add a new entry.

where &'k K: TryInto<Value<'k>>, <&'k K as TryInto<Value<'k>>>::Error: Into<Error>, V: TryFrom<&'v Value<'v>>, <V as TryFrom<&'v Value<'v>>>::Error: Into<Error>, 'd: 'k + 'v,

Get the value for the given key.

pub fn signature(&self) -> &Signature

Get the signature of this Dict.

pub fn try_clone(&self) -> Result<Self, Error>

Try to clone the Dict.

pub fn iter(&self) -> impl Iterator<Item = (&Value<'k>, &Value<'v>)>

pub fn iter_mut(&mut self) -> impl Iterator<Item = (&Value<'k>, &mut Value<'v>)>

impl<'k, 'v> IntoIterator for Dict<'k, 'v>

type Item = (Value<'k>, Value<'v>)

type IntoIter = <BTreeMap<Value<'k>, Value<'v>> as IntoIterator>::IntoIter

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'k, 'v> Ord for Dict<'k, 'v>

fn cmp(&self, other: &Dict<'k, 'v>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.
