[−][src]Struct arrow::builder::PrimitiveArrayBuilder
Array builder for fixed-width primitive types
Methods
impl<T: ArrowPrimitiveType> PrimitiveArrayBuilder<T>[src]
impl<T: ArrowPrimitiveType> PrimitiveArrayBuilder<T>pub fn new(capacity: usize) -> Self[src]
pub fn new(capacity: usize) -> SelfCreates a new primitive array builder
pub fn capacity(&self) -> usize[src]
pub fn capacity(&self) -> usizeReturns the capacity of this builder measured in slots of type T
pub fn push(&mut self, v: T::Native) -> Result<()>[src]
pub fn push(&mut self, v: T::Native) -> Result<()>Pushes a value of type T into the builder
pub fn push_null(&mut self) -> Result<()>[src]
pub fn push_null(&mut self) -> Result<()>Pushes a null slot into the builder
pub fn push_option(&mut self, v: Option<T::Native>) -> Result<()>[src]
pub fn push_option(&mut self, v: Option<T::Native>) -> Result<()>Pushes an Option<T> into the builder
pub fn push_slice(&mut self, v: &[T::Native]) -> Result<()>[src]
pub fn push_slice(&mut self, v: &[T::Native]) -> Result<()>Pushes a slice of type T into the builder
Trait Implementations
impl<T: ArrowPrimitiveType> ArrayBuilder for PrimitiveArrayBuilder<T>[src]
impl<T: ArrowPrimitiveType> ArrayBuilder for PrimitiveArrayBuilder<T>type ArrayType = PrimitiveArray<T>
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) -> PrimitiveArray<T>[src]
fn finish(self) -> PrimitiveArray<T>Builds the PrimitiveArray
