Implementations

impl PlainDateTime

pub const MIN: Self

The smallest value that can be represented by PlainDateTime.

Depending on large-dates feature flag, value of this constant may vary.

1. With large-dates disabled it is equal to -9999-01-01 00:00:00.0
2. With large-dates enabled it is equal to -999999-01-01 00:00:00.0

// Assuming `large-dates` feature is enabled.
assert_eq!(PlainDateTime::MIN, datetime!(-999999-01-01 0:00));

pub const MAX: Self

The largest value that can be represented by PlainDateTime.

Depending on large-dates feature flag, value of this constant may vary.

1. With large-dates disabled it is equal to 9999-12-31 23:59:59.999_999_999
2. With large-dates enabled it is equal to 999999-12-31 23:59:59.999_999_999

// Assuming `large-dates` feature is enabled.
