Struct sqldatetime::Timestamp

#[repr(transparent)]
pub struct Timestamp(_);

Timestamp represents a valid time at a valid Gregorian date.

This is an SQL TIMESTAMP value, with the specification of fractional seconds to a precision of microseconds.

Implementations

impl Timestamp

pub const MIN: Self

The smallest timestamp that can be represented by Date, i.e. 0001-01-01 00:00:00.000000.

pub const MAX: Self

The largest timestamp that can be represented by Date, i.e. 9999-12-31 23:59:59.999999.
