Qian Bin	65ed1a6871	rlp, trie: faster trie node encoding (#24126) ... This change speeds up trie hashing and all other activities that require RLP encoding of trie nodes by approximately 20%. The speedup is achieved by avoiding reflection overhead during node encoding. The interface type trie.node now contains a method 'encode' that works with rlp.EncoderBuffer. Management of EncoderBuffers is left to calling code. trie.hasher, which is pooled to avoid allocations, now maintains an EncoderBuffer. This means memory resources related to trie node encoding are tied to the hasher pool. Co-authored-by: Felix Lange <fjl@twurst.com>	3 years ago
ucwong	687e4dc855	rlp: add WriteString method on EncoderBuffer (#24425) ... rlpgen outputs calls to this method for values of type string.	3 years ago
Felix Lange	9b93564e21	rlp/rlpgen: RLP encoder code generator (#24251) ... This change adds a code generator tool for creating EncodeRLP method implementations. The generated methods will behave identically to the reflect-based encoder, but run faster because there is no reflection overhead. Package rlp now provides the EncoderBuffer type for incremental encoding. This is used by generated code, but the new methods can also be useful for hand-written encoders. There is also experimental support for generating DecodeRLP, and some new methods have been added to the existing Stream type to support this. Creating decoders with rlpgen is not recommended at this time because the generated methods create very poor error reporting. More detail about package rlp changes: * rlp: externalize struct field processing / validation This adds a new package, rlp/internal/rlpstruct, in preparation for the RLP encoder generator. I think the struct field rules are subtle enough to warrant extracting this into their own package, even though it means that a bunch of adapter code is needed for converting to/from rlpstruct.Type. * rlp: add more decoder methods (for rlpgen) This adds new methods on rlp.Stream: - Uint64, Uint32, Uint16, Uint8, BigInt - ReadBytes for decoding into []byte - MoreDataInList - useful for optional list elements * rlp: expose encoder buffer (for rlpgen) This exposes the internal encoder buffer type for use in EncodeRLP implementations. The new EncoderBuffer type is a sort-of 'opaque handle' for a pointer to encBuffer. It is implemented this way to ensure the global encBuffer pool is handled correctly.	3 years ago
