Required Methods§

Source

fn get_field_count(&self) -> usize

Returns the number of fields in this row

Source

fn is_null_at(&self, pos: usize) -> Result<bool>

Returns true if the element is null at the given position

Source

fn get_boolean(&self, pos: usize) -> Result<bool>

Returns the boolean value at the given position

Source

fn get_byte(&self, pos: usize) -> Result<i8>

Returns the byte value at the given position

Source

fn get_short(&self, pos: usize) -> Result<i16>

Returns the short value at the given position

Source

fn get_int(&self, pos: usize) -> Result<i32>

Returns the integer value at the given position

Source

fn get_long(&self, pos: usize) -> Result<i64>

Returns the long value at the given position

Source

fn get_float(&self, pos: usize) -> Result<f32>

Returns the float value at the given position

Source

fn get_double(&self, pos: usize) -> Result<f64>

Returns the double value at the given position

Source

fn get_char(&self, pos: usize, length: usize) -> Result<&str>

Returns the string value at the given position with fixed length

Source

fn get_string(&self, pos: usize) -> Result<&str>

Returns the string value at the given position

Source

fn get_decimal( &self, pos: usize, precision: usize, scale: usize, ) -> Result<Decimal>

Returns the decimal value at the given position

Source

fn get_date(&self, pos: usize) -> Result<Date>

Returns the date value at the given position (date as days since epoch)

Source

fn get_time(&self, pos: usize) -> Result<Time>

Returns the time value at the given position (time as milliseconds since midnight)

Source

fn get_timestamp_ntz(&self, pos: usize, precision: u32) -> Result<TimestampNtz>

Returns the timestamp value at the given position (timestamp without timezone)

The precision is required to determine whether the timestamp value was stored in a compact representation (precision <= 3) or with nanosecond precision.

Source

fn get_timestamp_ltz(&self, pos: usize, precision: u32) -> Result<TimestampLtz>

Returns the timestamp value at the given position (timestamp with local timezone)

The precision is required to determine whether the timestamp value was stored in a compact representation (precision <= 3) or with nanosecond precision.
