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

• 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_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

• 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_day_time( timestamp: <TimestampSecondType as ArrowPrimitiveType>::Native, delta: <IntervalDayTimeType as ArrowPrimitiveType>::Native, tz: Tz ) -> Option<<TimestampSecondType as ArrowPrimitiveType>::Native>

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

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

Subtracts 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
