Struct sp_mmr_primitives::OpaqueLeaf
source · pub struct OpaqueLeaf(pub Vec<u8>);
Expand description
A helper type to allow using arbitrary SCALE-encoded leaf data in the RuntimeApi.
The point is to be able to verify MMR proofs from external MMRs, where we don’t know the exact leaf type, but it’s enough for us to have it SCALE-encoded.
Note the leaf type should be encoded in its compact form when passed through this type. See FullLeaf documentation for details.
This type does not implement SCALE encoding/decoding on purpose to avoid confusion, it would have to be SCALE-compatible with the concrete leaf type, but due to SCALE limitations it’s not possible to know how many bytes the encoding of concrete leaf type uses.
Tuple Fields§
§0: Vec<u8>
Raw bytes of the leaf type encoded in its compact form.
NOTE it DOES NOT include length prefix (like Vec<u8>
encoding would).
Implementations§
