pub struct MapBuilder {
    map: IndexMap<Value, Value>,
    next_key: Option<Value>,
}

Accumulates key-value pairs for maps and structs.

Fields

Trait Implementations

impl SerializeMap for MapBuilder

type Ok = Value

Must match the Ok type of our Serializer.

type Error = Error

Must match the Error type of our Serializer.

fn serialize_key<T: ?Sized + Serialize>(&mut self, k: &T) -> Result<(), Error>

Serialize a map key.

fn serialize_value<T: ?Sized + Serialize>(&mut self, v: &T) -> Result<(), Error>

Serialize a map value.

fn end(self) -> Result<Value, Error>

Finish serializing a map.

fn serialize_entry<K, V>( &mut self, key: &K, value: &V, ) -> Result<(), Self::Error>

where K: Serialize + ?Sized, V: Serialize + ?Sized,

Serialize a map entry consisting of a key and a value.
