Provided Methods

fn bin_slice( &self, offset: &Column, length: &Column, ) -> Result<ChunkedArray<BinaryType>, PolarsError>

Slice the binary values.

Determines a slice starting from offset and with length length of each of the elements. offset can be negative, in which case the start counts from the end of the bytes.

fn bin_head(&self, n: &Column) -> Result<ChunkedArray<BinaryType>, PolarsError>

Slice the first n bytes of the binary value.

Determines a slice starting at the beginning of the binary data up to offset n of each element. n can be negative, in which case the slice ends n bytes from the end.

fn bin_tail(&self, n: &Column) -> Result<ChunkedArray<BinaryType>, PolarsError>

Slice the last n bytes of the binary value.

Determines a slice starting at offset n of each element. n can be negative, in which case the slice begins n bytes from the start.

fn contains(&self, lit: &[u8]) -> ChunkedArray<BooleanType>

Check if binary contains given literal

fn contains_chunked( &self, lit: &ChunkedArray<BinaryType>, ) -> Result<ChunkedArray<BooleanType>, PolarsError>

fn ends_with(&self, sub: &[u8]) -> ChunkedArray<BooleanType>

Check if strings ends with a substring

fn starts_with(&self, sub: &[u8]) -> ChunkedArray<BooleanType>

Check if strings starts with a substring

fn starts_with_chunked( &self, prefix: &ChunkedArray<BinaryType>, ) -> Result<ChunkedArray<BooleanType>, PolarsError>

fn ends_with_chunked( &self, suffix: &ChunkedArray<BinaryType>, ) -> Result<ChunkedArray<BooleanType>, PolarsError>

fn size_bytes(&self) -> ChunkedArray<UInt32Type>

Get the size of the binary values in bytes.

fn hex_decode( &self, strict: bool, ) -> Result<ChunkedArray<BinaryType>, PolarsError>

fn hex_encode(&self) -> Series

fn base64_decode( &self, strict: bool, ) -> Result<ChunkedArray<BinaryType>, PolarsError>

fn base64_encode(&self) -> Series

fn reinterpret( &self, dtype: &DataType, is_little_endian: bool, ) -> Result<Series, PolarsError>

fn _reinterpret_inner( &self, dtype: &DataType, is_little_endian: bool, ) -> Result<Vec<Box<dyn Array>>, PolarsError>
