[−][src]Struct arrow::array::BinaryArray
A special type of ListArray whose elements are binaries.
Methods
impl BinaryArray[src]
impl BinaryArraypub fn get_value(&self, i: i64) -> &[u8][src]
pub fn get_value(&self, i: i64) -> &[u8]Returns the element at index i as a byte slice.
pub fn get_string(&self, i: i64) -> String[src]
pub fn get_string(&self, i: i64) -> StringReturns the element at index i as a string.
Note this doesn't do any bound checking, for performance reason.
pub fn value_offset(&self, i: i64) -> i32[src]
pub fn value_offset(&self, i: i64) -> i32Returns the offset for the element at index i.
Note this doesn't do any bound checking, for performance reason.
pub fn value_length(&self, i: i64) -> i32[src]
pub fn value_length(&self, i: i64) -> i32Returns the length for the element at index i.
Note this doesn't do any bound checking, for performance reason.
