type mismatch in example

[ub-tech]

Hi - I tried to implement the example from the ReadMe but continue to receive this error. Any thoughts/help would be much appreciated. Thank you.

let proof = tree.create_proof(&B256::from(U256::from(i))).unwrap();
| ------------ ^^^^^^^^^^^^^^^^^^^^^^^^^^ expected FixedBytes<32>, found a different FixedBytes<32>

mismatched types
FixedBytes<32> and FixedBytes<32> have similar names, but are actually distinct types
perhaps two different versions of crate alloy_primitives are being used?

hey first suggest to upgrade to latest version, which is synced with alloy (v0.1.1) -- binded with alloy-primitives(v0.7.6) behind.

I suppose your project's primitive type version and alloy-merkle-tree primitive version was mismatched ( prob it was v0.7.6 vs v0.6.4 conflict -- I had experiment this recently)

so check out for latest version of this library which is v0.6.0 and if u still have issue lmk and share me the Cargo.toml of alloy related dependencies versions.
