WebSep 7, 2024 · I have a flatbuffers schema with many nested tables. In the Typescript flatbuffers I was able to have each table expose a to_offset function that returned the WIPOffset for the table on creation time. Then I could assign the result to the nested field in a higher level type, and it worked very well. In the Rust flatbuffers I cannot make this … WebUsage in C++. Include the header flexbuffers.h, which in turn depends on flatbuffers.h and util.h. To create a buffer: flexbuffers::Builder fbb; fbb.Int (13); fbb.Finish (); You create any value, followed by Finish. Unlike FlatBuffers which requires the root value to be a table, here any value can be the root, including a lonely int value.
WebAug 21, 2024 · 1 Answer. You can't simply copy a sub-table out of a larger FlatBuffer byte-wise, since this data is not necessarily contiguous. The best workaround is to instead make Bar store a [FooBuffer] where table FooBuffer { buf: [byte] (nested_flatbuffer: Foo) }. When you construct one of these, you construct each Foo into its own FlatBufferBuilder and ...
