[−][src]Struct arrow::array::LargeBinaryBuilder
Implementations
impl LargeBinaryBuilder
[src]
pub fn new(capacity: usize) -> Self
[src]
Creates a new LargeBinaryBuilder
, capacity
is the number of bytes in the values
array
pub fn append_byte(&mut self, value: u8) -> Result<()>
[src]
Appends a single byte value into the builder's values array.
Note, when appending individual byte values you must call append
to delimit each
distinct list value.
pub fn append_value(&mut self, value: &[u8]) -> Result<()>
[src]
Appends a byte slice into the builder.
Automatically calls the append
method to delimit the slice appended in as a
distinct array element.
pub fn append(&mut self, is_valid: bool) -> Result<()>
[src]
Finish the current variable-length list array slot.
pub fn append_null(&mut self) -> Result<()>
[src]
Append a null value to the array.
pub fn finish(&mut self) -> LargeBinaryArray
[src]
Builds the LargeBinaryArray
and reset this builder.
Trait Implementations
impl ArrayBuilder for LargeBinaryBuilder
[src]
fn as_any(&self) -> &dyn Any
[src]
Returns the builder as a non-mutable Any
reference.
fn as_any_mut(&mut self) -> &mut dyn Any
[src]
Returns the builder as a mutable Any
reference.
fn append_data(&mut self, data: &[ArrayDataRef]) -> Result<()>
[src]
Appends data from other arrays into the builder
This is most useful when concatenating arrays of the same type into a builder.
fn data_type(&self) -> DataType
[src]
Returns the data type of the builder
This is used for validating array data types in append_data
fn into_box_any(self: Box<Self>) -> Box<dyn Any>
[src]
Returns the boxed builder as a box of Any
.
fn len(&self) -> usize
[src]
Returns the number of array slots in the builder
fn is_empty(&self) -> bool
[src]
Returns whether the number of array slots is zero
fn finish(&mut self) -> ArrayRef
[src]
Builds the array and reset this builder.
