Struct arrow::array::FixedSizeBinaryArray [−][src]
pub struct FixedSizeBinaryArray { /* fields omitted */ }
Expand description
A type of FixedSizeListArray
whose elements are binaries.
Implementations
impl FixedSizeBinaryArray
[src]
impl FixedSizeBinaryArray
[src]pub fn value_offset(&self, i: usize) -> i32
[src]
pub fn value_offset(&self, i: usize) -> i32
[src]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) -> i32
[src]
pub fn value_length(&self) -> i32
[src]Returns the length for an element.
All elements have the same length as the array is a fixed size.
pub fn value_data(&self) -> Buffer
[src]
pub fn value_data(&self) -> Buffer
[src]Returns a clone of the value data buffer
pub fn try_from_sparse_iter<T, U>(iter: T) -> Result<Self, ArrowError> where
T: Iterator<Item = Option<U>>,
U: AsRef<[u8]>,
[src]
pub fn try_from_sparse_iter<T, U>(iter: T) -> Result<Self, ArrowError> where
T: Iterator<Item = Option<U>>,
U: AsRef<[u8]>,
[src]Create an array from an iterable argument of sparse byte slices.
Sparsity means that items returned by the iterator are optional, i.e input argument can
contain None
items.
Examles
use arrow::array::FixedSizeBinaryArray; let input_arg = vec![ None, Some(vec![7, 8]), Some(vec![9, 10]), None, Some(vec![13, 14]), None, ]; let array = FixedSizeBinaryArray::try_from_sparse_iter(input_arg.into_iter()).unwrap();
Errors
Returns error if argument has length zero, or sizes of nested slices don’t match.
pub fn try_from_iter<T, U>(iter: T) -> Result<Self, ArrowError> where
T: Iterator<Item = U>,
U: AsRef<[u8]>,
[src]
pub fn try_from_iter<T, U>(iter: T) -> Result<Self, ArrowError> where
T: Iterator<Item = U>,
U: AsRef<[u8]>,
[src]Create an array from an iterable argument of byte slices.
Examles
use arrow::array::FixedSizeBinaryArray; let input_arg = vec![ vec![1, 2], vec![3, 4], vec![5, 6], ]; let array = FixedSizeBinaryArray::try_from_iter(input_arg.into_iter()).unwrap();
Errors
Returns error if argument has length zero, or sizes of nested slices don’t match.

[src]
impl Array for FixedSizeBinaryArray
[src]fn get_buffer_memory_size(&self) -> usize
[src]
fn get_buffer_memory_size(&self) -> usize
[src]Returns the total number of bytes of memory occupied by the buffers owned by this FixedSizeBinaryArray.
fn get_array_memory_size(&self) -> usize
[src]
fn get_array_memory_size(&self) -> usize
[src]Returns the total number of bytes of memory occupied physically by this FixedSizeBinaryArray.
fn data_ref(&self) -> &ArrayData
[src]
fn data_ref(&self) -> &ArrayData
[src]Returns a reference-counted pointer to the underlying data of this array.
fn slice(&self, offset: usize, length: usize) -> ArrayRef
[src]
fn slice(&self, offset: usize, length: usize) -> ArrayRef
[src]Returns a zero-copy slice of this array with the indicated offset and length. Read more
fn offset(&self) -> usize
[src]
fn offset(&self) -> usize
[src]Returns the offset into the underlying data used by this array(-slice).
Note that the underlying data can be shared by many arrays.
This defaults to 0
. Read more
fn is_null(&self, index: usize) -> bool
[src]
fn is_null(&self, index: usize) -> bool
[src]Returns whether the element at index
is null.
When using this function on a slice, the index is relative to the slice. Read more
fn is_valid(&self, index: usize) -> bool
[src]
fn is_valid(&self, index: usize) -> bool
[src]Returns whether the element at index
is not null.
When using this function on a slice, the index is relative to the slice. Read more
fn null_count(&self) -> usize
[src]
fn null_count(&self) -> usize
[src]Returns the total number of null values in this array. Read more
fn to_raw(&self) -> Result<(*const FFI_ArrowArray, *const FFI_ArrowSchema)>
[src]
fn to_raw(&self) -> Result<(*const FFI_ArrowArray, *const FFI_ArrowSchema)>
[src]returns two pointers that represent this array in the C Data Interface (FFI)
