Is there any rust crate available for building merkle tree?

help
1

I have an vector or numbers. I need to build a merkle root out of it. Is there any crate available for this purpose?

2

Does merkletree provide what you are after?

3

I have gone through it, but i could't find anything that can convert a vector of elements into merkle leaf

4

Isn't that just MerkleTree::new(elements)? Assumption based on this function from merkletree's test suite.

merkle trees have a wide variety of incompatible definitions from different block chains. It's kind of a choose your own adventure situation.

I have a vector of String

Transform your string into [u8; 32]. E.g. with a hash function.
