Struct sp_mmr_primitives::Compact
source · pub struct Compact<H, T> {
pub tuple: T,
/* private fields */
}
Expand description
A composition of multiple leaf elements with compact form representation.
When composing together multiple LeafDataProviders you will end up with
a tuple of LeafData
that each element provides.
However this will cause the leaves to have significant size, while for some use cases it will be enough to prove only one element of the tuple. That’s the rationale for Compact struct. We wrap each element of the tuple into DataOrHash and each tuple element is hashed first before constructing the final hash of the entire tuple. This allows you to replace tuple elements you don’t care about with their hashes.
Fields§
§tuple: T
Internal tuple representation.
