ser-write-msgpack

This crate provides a no_std friendly MessagePack serializers for serde using SerWrite as a writer and a deserializer for convenience.

Usage

[dependencies]
ser-write-msgpack = { version = "0.3", default-features = false }

Serializer

ser-write-msgpack comes with 3 serializers:

• to_writer_compact - serializes structs to arrays and enum variants as indexes,
• to_writer - serializes structs to maps with fields and enum variants as indexes,
• to_writer_named - serializes structs to maps with field names and enum variants as strings.

Features:

• std enables std library,
• alloc enables alloc library,

With alloc or std feature enabled serde::ser::Serializer::collect_str method is implemented using intermediate String.

Otherwise Serializer::collect_str is implemented by formatting a string twice, once to count the string size and the second time to actually write it.

Deserializer

The MessagePack deserializer expects a MessagePack encoded slice of bytes. &str or &[u8] types deserialize using (ZERO-COPY) references from the provided slice.

• from_slice - deserializes MessagePack data from a slice of bytes
• from_slice_split_tail - deserializes MessagePack data from a slice of bytes returning a remaining portion of the input slice

Deserializer supports self-describing formats.

Deserializer deserializes structs from both maps and arrays using either strings or indexes as variant or field identifiers.

Rust Version Requirements

ser-write-msgpack requires Rustc version 1.81 or greater.
