Macro Serde

macro_rules! Serde {
    (*) => { ... };
    ($($expecting:tt),+ $(,)?) => { ... };
}

Constructor of Serde types / instances.

The macro accepts a comma-separated list of expected basic types from the following set: bool, int, float, str, array, object. As a shortcut, Serde![*] signals to accept any input.

Examples

#[derive(Debug)]
struct ComplexType {
    // ...
}

impl Serialize for ComplexType {
    // Complex serialization logic...
}

impl<'de> Deserialize<'de> for ComplexType {
    // Complex deserialization logic...
}

#[derive(DescribeConfig, DeserializeConfig)]
struct TestConfig {
    /// Will try to deserialize any integer, string or object delegating
    /// to the `Deserialize` impl. Will error on other inputs (e.g., arrays).
    #[config(with = Serde![int, str, object])]
    complex_param: ComplexType,
    #[config(with = Serde![*])]
    anything: serde_json::Value,
