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