0.19.1

• Support deriving ElasticDateFormat without requiring you to add chrono to your own crate (#84)
• Support deriving ElasticType without requiring you to add serde to your own crate (#84)

0.19.0

This release refactors Date to start reducing dependence on chrono::DateTime, and to make sure date formats aren't implicitly changed. Some of these changes might turn out to be too restrictive and may be reverted in the future (allowing formats to change without explicit conversions).

• Change remap methods to be static methods instead of instance methods
• Add DateExpr for supporting date math expressions

Changes to Date

• Change Date<F, M = DefaultDateMapping<F>> to Date<M>. So you can't just write Date<EpochMillis> anymore, it needs to be Date<DefaultDateMapping<EpochMillis>>. This simplifies the generics, and makes Date easier to work with. To get the ergonomics of Date<EpochMillis> back, you can use type aliases:

// For default date types with just a single format
type MyDateType = Date<DefaultDateMapping<EpochMillis>>;

// For default date types with any format
type MyDateType<F> = Date<DefaultDateMappinng<F>>;

• Adds a DateValue and FormattableDateValue type
• Use DateValue in the DateFormat::parse and DateFormat::format methods instead of chrono::DateTime
• Remove the conversion from chrono::DateTime into Date<M> unless M::Format = ChronoFormat. This is because chrono::DateTime is already mappable with the ChronoFormat, so to make sure that formats aren't implicitly changed, you need to convert a chrono::DateTime into a DateValue first, which doesn't have any format:

Before:

let date = Date::from(chrono_date);

After:

let date = Date::from(DateValue::from(chrono_date));

Changes to GeoPoint

• Like Date, GeoPoint<F, M = DefaultGeoPointMapping<F>> has been changed to GeoPoint<M>. Use the same type aliases approach for ergonomics
