pub struct DecimalArray { /* fields omitted */ }
Expand description
A type of DecimalArray
whose elements are binaries.
Implementations
impl DecimalArray
[src]
impl DecimalArray
[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 from_fixed_size_list_array(
v: FixedSizeListArray,
precision: usize,
scale: usize
) -> Self
[src]
v: FixedSizeListArray,
precision: usize,
scale: usize
) -> Self
pub fn precision(&self) -> usize
[src]
pub fn scale(&self) -> usize
[src]
Trait Implementations
impl Array for DecimalArray
[src]
impl Array for DecimalArray
[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 DecimalArray.
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 DecimalArray.
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)
