[−][src]Struct arrow::array::PrimitiveBuilder
Array builder for fixed-width primitive types
Methods
impl<T: ArrowPrimitiveType> PrimitiveBuilder<T>
[src]
pub fn new(capacity: usize) -> Self
[src]
Creates a new primitive array builder
pub fn capacity(&self) -> usize
[src]
Returns the capacity of this builder measured in slots of type T
pub fn append_value(&mut self, v: T::Native) -> Result<()>
[src]
Appends a value of type T
into the builder
pub fn append_null(&mut self) -> Result<()>
[src]
Appends a null slot into the builder
pub fn append_option(&mut self, v: Option<T::Native>) -> Result<()>
[src]
Appends an Option<T>
into the builder
pub fn append_slice(&mut self, v: &[T::Native]) -> Result<()>
[src]
Appends a slice of type T
into the builder
pub fn finish(&mut self) -> PrimitiveArray<T>
[src]
Builds the PrimitiveArray
and reset this builder.
