[−][src]Struct arrow::builder::BinaryArrayBuilder
Array builder for BinaryArray
Methods
impl BinaryArrayBuilder[src]
impl BinaryArrayBuilderpub fn new(capacity: usize) -> Self[src]
pub fn new(capacity: usize) -> SelfCreates a new BinaryArrayBuilder, capacity is the number of bytes in the values array
pub fn push(&mut self, value: u8) -> Result<()>[src]
pub fn push(&mut self, value: u8) -> Result<()>Pushes a single byte value into the builder's values array.
Note, when pushing individual byte values you must call append to delimit each
distinct list value.
pub fn push_string(&mut self, value: &str) -> Result<()>[src]
pub fn push_string(&mut self, value: &str) -> Result<()>Pushes a &String or &str into the builder.
Automatically calls the append method to delimit the string pushed in as a distinct
array element.
pub fn append(&mut self, is_valid: bool) -> Result<()>[src]
pub fn append(&mut self, is_valid: bool) -> Result<()>Finish the current variable-length list array slot.
Trait Implementations
impl ArrayBuilder for BinaryArrayBuilder[src]
impl ArrayBuilder for BinaryArrayBuildertype ArrayType = BinaryArray
The type of array that this builder creates
fn into_any(self) -> Box<dyn Any>[src]
fn into_any(self) -> Box<dyn Any>Returns the builder as an owned Any type so that it can be downcast to a specific
implementation before calling it's finish method.
fn len(&self) -> usize[src]
fn len(&self) -> usizeReturns the number of array slots in the builder
fn finish(self) -> BinaryArray[src]
fn finish(self) -> BinaryArrayBuilds the BinaryArray
