#[derive(thiserror::Error, Debug, Display)]
#[allow(dead_code)]
pub(crate) enum SerdeError {

this can be confusing - there is a serde crate, which defines a serde_json::Error object already. Maybe just rename ?

Suggestion:

SerializationError

crates/committer/src/storage/serde_trait.rs line 4 at r1 (raw file):

use crate::storage::storage_trait::{StorageError, StorageKey, StorageValue};

pub(crate) trait serde_trait {

1. don't use snake case for traits - capital camelcase (pascal case?)
2. I would use "Serializable", not serde, because serde is an external crate

Suggestion:

pub(crate) trait Serializable {

crates/committer/src/storage/serde_trait.rs line 4 at r1 (raw file):

use crate::storage::storage_trait::{StorageError, StorageKey, StorageValue};

pub(crate) trait serde_trait {

add a db_key(&self) -> StorageKey method

crates/committer/src/storage/serde_trait.rs line 8 at r1 (raw file):

    fn serialize(&self) -> Result<StorageValue, SerdeError::Serialize>;
    /// Deserializes the given value.
    fn deserialize(vale: StorageValue) -> Result<Self, SerdeError::Deserialize>;

typo

Suggestion:

value
