- 117-148: The example provided in the documentation for
get_default_empty_recordis clear and demonstrates the function's usage effectively. It's good practice to include such examples in the documentation, as it helps users understand how to use the function in their code. No changes are needed here, but ensure that the documentation stays up-to-date if the function's behavior changes in the future.

Hi @lucatrv ! First and foremost, thank you for your contribution! Can you please provide a use case for this function to be useful? I am not sure I understand why, for example, and when, I would use it. For example, the code you provided: #[derive(serde::Deserialize, PartialEq, Debug)]
struct Record {
#[serde(default = "default_string")]
label: String,
#[serde(default = "default_f64")]
value: f64,
}
fn default_string() -> String {
String::from("default")
}
fn default_f64() -> f64 {
1.0
}
let empty_record = get_default_empty_record::<Record>().unwrap();
assert_eq!(
empty_record,
Record {
label: String::from("default"),
value: 1.0
}
);How is it different from this, without using #[derive(serde::Deserialize, PartialEq, Debug)]
struct Record {
label: String,
value: f64,
}
impl Default for Record {
fn default() -> Self {
Self {
label: default_string(),
value: default_f64(),
}
}
}
fn default_string() -> String {
String::from("default")
}
fn default_f64() -> f64 {
1.0
}
let empty_record = Record::default();
assert_eq!(
empty_record,
Record {
label: String::from("default"),
value: 1.0
}
); |

@iddm I agree that the example above is trivial and can easily be implemented as you showed, however it was intended just to show how the Please consider however that often we deal with long deserialize structs having most fields implementing the In general, any time the From another point of view, IMHO what you wrote could also be applied to most helping functions. For instance we could certainly live for instance also without the |

- 117-168: The implementation of
get_default_serde_recordis concise and leverages Serde's deserialization capabilities effectively to instantiate a default record. This approach is particularly useful when combined with Serde's#[serde(default = "path")]attribute, as it simplifies struct initialization without manually implementing theDefaulttrait. The documentation and example provided are clear and demonstrate the function's utility well.However, it's important to ensure that all potential error cases are handled appropriately when using this function in a broader context. Specifically, consider adding error handling advice in the documentation for consumers of this API, as deserialization errors can occur for various reasons (e.g., missing required fields, type mismatches).
Overall, the addition of
get_default_serde_recordenhances the library's functionality by providing a convenient way to obtain default instances of structs that are compatible with Serde's deserialization process.
- 214-251: > 📝 NOTE
This review was outside the diff hunks and was mapped to the diff hunk with the greatest overlap. Original lines [174-250]
The test cases provided for
get_default_serde_recordandserde_introspectfunctions are comprehensive and cover the basic functionality expected from these utilities. The tests validate the correct instantiation of structs with default values and the introspection of serialization names for both structs and enums.One suggestion for improvement is to include more edge cases in the test suite. For example, testing structs with more complex nested structures or enums with associated values could provide additional confidence in the robustness of these functions. Additionally, considering negative test cases, such as attempting to deserialize a struct with missing required fields, could help document the expected behavior in error scenarios.
Overall, the tests are well-structured and serve their purpose of validating the functionality introduced in this PR.
I did as suggested, see if you like it now otherwise please feel free to elaborate further as you will. |
