Struct DecimalBuilder 

pub struct DecimalBuilder { /* private fields */ }

An ArrayBuilder for Decimal typed arrays.

The output will be a new DecimalArray holding values of T. Any value that is a valid decimal type can be appended to the builder and it will be immediately coerced into the target type.

Implementations

impl DecimalBuilder

pub fn new<T: NativeDecimalType>( precision: u8, scale: i8, nullability: Nullability, ) -> Self

pub fn with_capacity<T: NativeDecimalType>( capacity: usize, decimal: DecimalDType, nullability: Nullability, ) -> Self

impl DecimalBuilder

pub fn append_value<V: NativeDecimalType>(&mut self, value: V)

pub fn append_option<V: NativeDecimalType>(&mut self, value: Option<V>)

pub fn append_mask(&mut self, mask: Mask)

Append a Mask to the null buffer.

impl DecimalBuilder

pub fn finish_into_decimal(&mut self) -> DecimalArray
