Evgeniy Stratonikov	bd2b1a0521	mpt: add Size method to trie nodes ... Knowing serialized size of the node is useful for preallocating byte-slice in advance. Signed-off-by: Evgeniy Stratonikov <evgeniy@nspcc.ru>	2021-08-06 12:01:16 +03:00
Evgeniy Stratonikov	db80ef28df	mpt: move empty hash node in a separate type ... We use them quite frequently (consider children for a new branch node) and it is better to get rid of unneeded allocations. Signed-off-by: Evgeniy Stratonikov <evgeniy@nspcc.ru>	2021-08-06 12:01:16 +03:00
Evgeniy Stratonikov	5b1f6207de	mpt: reduce max key length ... The constant used is actually a nibbled-path restriction. Clarify this and make them private.	2021-06-04 11:09:17 +03:00
Anna Shaleva	7f038bd465	mpt: split HashNode in two types ... First type is non-empty HashNode, and the second one is an Empty node.	2021-04-01 10:19:57 +03:00
Anna Shaleva	7dc9f0bde2	mpt: swap Leaf and Node types	2021-04-01 10:17:08 +03:00
Evgenii Stratonikov	fd9ff4102a	mpt: export func for decoding node with type ... `NodeObject` can contain auxilliary fields and shouldn't be used from outside.	2020-11-19 12:25:43 +03:00
Roman Khimov	475bf2445a	mpt: restructure nodes a bit, implement serialization and hash cache ... It drastically reduces the number of allocations and hash calculations. Signed-off-by: Evgenii Stratonikov <evgeniy@nspcc.ru>	2020-07-30 12:42:15 +03:00
Evgenii Stratonikov	f0b85f8af7	mpt: implement JSON marshaling/unmarshaling ... Because there is no distinct type field in JSONized nodes, distinction is made via payload itself, thus all unmarshaling is done via NodeObject.

Evgenii Stratonikov	dc6741bce7	mpt: implement MPT trie ... MPT is a trie with a branching factor = 16, i.e. it consists of sequences in 16-element alphabet. Signed-off-by: Evgenii Stratonikov <evgeniy@nspcc.ru>	2020-07-30 12:42:15 +03:00
