The Weekdays crate provides a simple Weekdays type for representing days of the week bit-mapped in a single byte, and functionality for working with them.

This is particularly useful when representing a set of days in a database field or similar.

Each bit represents a day of the week. The bits are ordered from most significant to least significant, starting from Monday, with the least significant bit representing Sunday.

| Tuesday
| | Wednesday
| | | Thursday
| | | | Friday
| | | | | Saturday

The following feature flags are available:

• chrono: Enables conversion to and from the Weekday type from the Chrono crate.
• postgres: Implements the ToSql and FromSql traits for use with tokio-postgres.
• serde: Enables serialisation and deserialisation with Serde by implementing the Serialize and Deserialize traits.

Additionally:

• default: Has no features enabled.
• full: Enables all features.

When using the postgres feature, the expectation is that the database field will be configured as BITS(7), i.e. a 7-bit bitfield.
