Expand description
LengthOp defines how to process the key and value of the LeafOp to include length information. After encoding the length with the given algorithm, the length will be prepended to the key and value bytes. (Each one with it’s own encoded length)
Variants
NoPrefix
NO_PREFIX don’t include any length info
VarProto
VAR_PROTO uses protobuf (and go-amino) varint encoding of the length
VarRlp
VAR_RLP uses rlp int encoding of the length
Fixed32Big
FIXED32_BIG uses big-endian encoding of the length as a 32 bit integer
Fixed32Little
FIXED32_LITTLE uses little-endian encoding of the length as a 32 bit integer
Fixed64Big
FIXED64_BIG uses big-endian encoding of the length as a 64 bit integer
Fixed64Little
FIXED64_LITTLE uses little-endian encoding of the length as a 64 bit integer
Require32Bytes
REQUIRE_32_BYTES is like NONE, but will fail if the input is not exactly 32 bytes (sha256 output)
Require64Bytes
REQUIRE_64_BYTES is like NONE, but will fail if the input is not exactly 64 bytes (sha512 output)
