1*890232f2SAndroid Build Coastguard Worker# Flexbuffers 2*890232f2SAndroid Build Coastguard Worker 3*890232f2SAndroid Build Coastguard Worker[Flexbuffers](https://google.github.io/flatbuffers/flexbuffers.html) is a 4*890232f2SAndroid Build Coastguard Workerschema-less binary format developed at Google. FlexBuffers can be accessed 5*890232f2SAndroid Build Coastguard Workerwithout parsing, copying, or allocation. This is a huge win for efficiency, 6*890232f2SAndroid Build Coastguard Workermemory friendly-ness, and allows for unique use cases such as mmap-ing large 7*890232f2SAndroid Build Coastguard Workeramounts of free-form data. 8*890232f2SAndroid Build Coastguard Worker 9*890232f2SAndroid Build Coastguard WorkerFlexBuffers' design and implementation allows for a very compact encoding, 10*890232f2SAndroid Build Coastguard Workerwith automatic sizing of containers to their smallest possible representation 11*890232f2SAndroid Build Coastguard Worker(8/16/32/64 bits). Many values and offsets can be encoded in just 8 bits. 12*890232f2SAndroid Build Coastguard Worker 13*890232f2SAndroid Build Coastguard WorkerFlexBuffers supports [Serde](https://serde.rs/) for automatically serializing 14*890232f2SAndroid Build Coastguard WorkerRust data structures into its binary format. 15*890232f2SAndroid Build Coastguard Worker 16*890232f2SAndroid Build Coastguard Worker## See Examples for Usage: 17*890232f2SAndroid Build Coastguard Worker* [Example](https://github.com/google/flatbuffers/blob/master/samples/sample_flexbuffers.rs) 18*890232f2SAndroid Build Coastguard Worker* [Serde Example](https://github.com/google/flatbuffers/blob/master/samples/sample_flexbuffers_serde.rs) 19*890232f2SAndroid Build Coastguard Worker* [Documentation](https://docs.rs/flexbuffers) 20*890232f2SAndroid Build Coastguard Worker 21*890232f2SAndroid Build Coastguard WorkerFlexbuffers is the schema-less cousin of 22*890232f2SAndroid Build Coastguard Worker[Flatbuffers](https://google.github.io/flatbuffers/). 23
