    }
}

This is a new code.
This is the goal of this PR.

Code quote:

impl TryFrom<&CasmContractClass> for ContractClassV1 {
    type Error = ProgramError;

    fn try_from(class: &CasmContractClass) -> Result<Self, Self::Error> {
        try_from_casm_contrcat_class_internal(
            &class.bytecode,
            &class.hints,
            &class.entry_points_by_type,
            class.bytecode_segment_lengths.clone(),
            &class.compiler_version,
        )
    }

    sn_api_to_cairo_vm_program(deprecated_program)
        .map_err(|err| DeserializationError::custom(err.to_string()))
}

This is not a new code. This is only an artifact of the diff showing the body of the new function (try_from_casm_contrcat_class_internal) as the body of impl TryFrom<CasmContractClass> for ContractClassV1

Code quote:

// V0 utilities.

/// Converts the program type from SN API into a Cairo VM-compatible type.
pub fn deserialize_program<'de, D: Deserializer<'de>>(
    deserializer: D,
) -> Result<Program, D::Error> {
    let deprecated_program = DeprecatedProgram::deserialize(deserializer)?;
    sn_api_to_cairo_vm_program(deprecated_program)
        .map_err(|err| DeserializationError::custom(err.to_string()))
}
