Enum chrono::Weekday

pub enum Weekday {
    Mon,
    Tue,
    Wed,
    Thu,
    Fri,
    Sat,
    Sun,
}

The day of week.

The order of the days of week depends on the context. (This is why this type does not implement PartialOrd or Ord traits.) One should prefer *_from_monday or *_from_sunday methods to get the correct result.

impl FromPrimitive for Weekday

Any weekday can be represented as an integer from 0 to 6, which equals to Weekday::num_days_from_monday in this implementation. Do not heavily depend on this though; use explicit methods whenever possible.

fn from_i64(n: i64) -> Option<Weekday>

fn from_u64(n: u64) -> Option<Weekday>

Convert an u64 to return an optional value of this type. If the type cannot be represented by this value, the None is returned.

fn from_isize(n: isize) -> Option<Self>

Convert an isize to return an optional value of this type. If the value cannot be represented by this value, the None is returned.

fn from_i8(n: i8) -> Option<Self>

Convert an i8 to return an optional value of this type. If the type cannot be represented by this value, the None is returned.

fn from_i16(n: i16) -> Option<Self>

Convert an i16 to return an optional value of this type. If the type cannot be represented by this value, the None is returned.

fn from_i32(n: i32) -> Option<Self>

Convert an i32 to return an optional value of this type. If the type cannot be represented by this value, the None is returned.

fn from_usize(n: usize) -> Option<Self>

Convert a usize to return an optional value of this type. If the type cannot be represented by this value, the None is returned.

fn from_u8(n: u8) -> Option<Self>
