pub struct Serializer<W, F = CompactFormatter> { /* private fields */ }
Expand description

A structure for serializing Rust values into JSON.

Implementations§

Creates a new JSON serializer.

Creates a new JSON pretty print serializer.

Creates a new JSON visitor whose output will be written to the writer specified.

Unwrap the Writer from the Serializer.

Trait Implementations§

Serialize newtypes without an object wrapper.

The output type produced by this Serializer during successful serialization. Most serializers that produce text or binary output should set Ok = () and serialize into an io::Write or buffer contained within the Serializer instance. Serializers that build in-memory data structures may be simplified by using Ok to propagate the data structure around.
The error type when some error occurs during serialization.
Type returned from serialize_seq for serializing the content of the sequence.
Type returned from serialize_tuple for serializing the content of the tuple.
Type returned from serialize_tuple_struct for serializing the content of the tuple struct.
Type returned from serialize_tuple_variant for serializing the content of the tuple variant.
Type returned from serialize_map for serializing the content of the map.
Type returned from serialize_struct for serializing the content of the struct.
Type returned from serialize_struct_variant for serializing the content of the struct variant.
