Methods
impl<T: ArrowPrimitiveType> PrimitiveArrayBuilder<T>
[src]
impl<T: ArrowPrimitiveType> PrimitiveArrayBuilder<T>
pub fn new(capacity: usize) -> Self
[src]
pub fn new(capacity: usize) -> Self
Creates a new primitive array builder
pub fn capacity(&self) -> usize
[src]
pub fn capacity(&self) -> usize
Returns 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) -> usize
Returns the number of array slots in the builder
fn finish(self) -> PrimitiveArray<T>
[src]
fn finish(self) -> PrimitiveArray<T>
Builds the PrimitiveArray
