crates/starknet_committer/src/hash_function/hash.rs line 83 at r1 (raw file):

    let compiled_class_hash: &CompiledClassHash = compiled_class_hash_leaf.as_ref();
    let contract_class_leaf_version: Felt = Felt::from_hex(
        TreeHashFunctionImpl::CONTRACT_CLASS_LEAF_V0,

In the "global" namespace (TreeHashFunctionImpl), there is a constant defined only for compiled class hashes. In the same way, utils for compiled class hashes should be defined in the same place.

In addition, I prefer that the common place won't beTreeHashFunctionImpl. WDYT?

Code quote:

TreeHashFunctionImpl::CONTRACT_CLASS_LEAF_V0

    let contract_class_leaf_version: Felt = Felt::from_hex(
        TreeHashFunctionImpl::CONTRACT_CLASS_LEAF_V0,
    )

It's worth using the const function Felt::from_hex_unchecked for const strings.

Code quote:

    let contract_class_leaf_version: Felt = Felt::from_hex(
        TreeHashFunctionImpl::CONTRACT_CLASS_LEAF_V0,
    )

crates/starknet_committer/src/hash_function/hash.rs line 18 at r5 (raw file):

// The hex string corresponding to b'CONTRACT_CLASS_LEAF_V0' in big-endian.
pub const CONTRACT_CLASS_LEAF_V0: Felt =
    Felt::from_hex_unchecked("0x434f4e54524143545f434c4153535f4c4541465f5630");

this move of constants should have been a separate PR - broad change (many small diffs in different places), very easy to LGTM quickly, and self-contained

Code quote:

pub const CONTRACT_STATE_HASH_VERSION: Felt = Felt::ZERO;

// The hex string corresponding to b'CONTRACT_CLASS_LEAF_V0' in big-endian.
pub const CONTRACT_CLASS_LEAF_V0: Felt =
    Felt::from_hex_unchecked("0x434f4e54524143545f434c4153535f4c4541465f5630");

ditto

    fn as_ref(&self) -> &CompiledClassHash {

    }

also, can't you derive_more::AsRef it?

Suggestion:

    fn as_ref(&self) -> &Self {
        self
    }

Nope, derive_more is for trivial wrappers Outer(inner).
