toml-datetime-compat

Adds a functionality to easily convert between toml_datetime's and chrono's/time's types.

Both with the serde derive macros:

#[derive(Deserialize, Serialize)]
struct SomeDateTimes {
    #[serde(with = "toml_datetime_compat")]
    chrono_naive_date: chrono::NaiveDate,
    #[serde(with = "toml_datetime_compat")]
    chrono_naive_time: chrono::NaiveTime,
    #[serde(with = "toml_datetime_compat")]
    chrono_naive_date_time: chrono::NaiveDateTime,
    #[serde(with = "toml_datetime_compat")]
    chrono_date_time_utc: chrono::DateTime<chrono::Utc>,
    #[serde(with = "toml_datetime_compat")]
    chrono_date_time_offset: chrono::DateTime<chrono::FixedOffset>,
    #[serde(with = "toml_datetime_compat")]
    time_date: time::Date,
    #[serde(with = "toml_datetime_compat")]
    time_time: time::Time,
    #[serde(with = "toml_datetime_compat")]
    time_primitive_date_time: time::PrimitiveDateTime,
    #[serde(with = "toml_datetime_compat")]
    time_offset_date_time: time::OffsetDateTime,"#
}

And by introducing a new trait ToFromToml that adds to_toml and from_toml functions to the relevant structs from chrono and time.
