Implementations

impl TimestampSecondType

pub fn add_year_months( timestamp: <TimestampSecondType as ArrowPrimitiveType>::Native, delta: <IntervalYearMonthType as ArrowPrimitiveType>::Native, tz: Tz, ) -> Option<<TimestampSecondType as ArrowPrimitiveType>::Native>

Adds the given IntervalYearMonthType to an arrow TimestampSecondType.

Returns None when it will result in overflow.

Arguments

pub fn add_day_time( timestamp: <TimestampSecondType as ArrowPrimitiveType>::Native, delta: <IntervalDayTimeType as ArrowPrimitiveType>::Native, tz: Tz, ) -> Option<<TimestampSecondType as ArrowPrimitiveType>::Native>

Adds the given IntervalDayTimeType to an arrow TimestampSecondType.

Returns None when it will result in overflow.

Arguments

• timestamp - The date on which to perform the operation
• delta - The interval to add
• tz - The timezone in which to interpret timestamp

pub fn add_month_day_nano( timestamp: <TimestampSecondType as ArrowPrimitiveType>::Native, delta: <IntervalMonthDayNanoType as ArrowPrimitiveType>::Native, tz: Tz, ) -> Option<<TimestampSecondType as ArrowPrimitiveType>::Native>

Adds the given IntervalMonthDayNanoType to an arrow TimestampSecondType

Returns None when it will result in overflow.

Arguments

• timestamp - The date on which to perform the operation
• delta - The interval to add
• tz - The timezone in which to interpret timestamp

pub fn subtract_year_months( timestamp: <TimestampSecondType as ArrowPrimitiveType>::Native, delta: <IntervalYearMonthType as ArrowPrimitiveType>::Native, tz: Tz, ) -> Option<<TimestampSecondType as ArrowPrimitiveType>::Native>

Subtracts the given IntervalYearMonthType to an arrow TimestampSecondType

Returns None when it will result in overflow.

Arguments

Subtracts the given IntervalDayTimeType to an arrow TimestampSecondType

Returns None when it will result in overflow.

Arguments

• timestamp - The date on which to perform the operation
• delta - The interval to add
• tz - The timezone in which to interpret timestamp
