Implementations§

Source§

impl LargeStringArrayBuilder

Source

pub fn with_capacity( item_capacity: usize, data_capacity: usize, ) -> LargeStringArrayBuilder

Source

pub fn write<const CHECK_VALID: bool>( &mut self, column: &ColumnarValueRef<'_>, i: usize, )

Source

pub fn append_offset(&mut self)

Source

pub fn finish( self, null_buffer: Option<NullBuffer>, ) -> GenericByteArray<GenericStringType<i64>>

Finalize the builder into a concrete LargeStringArray.

§Panics

This method can panic when:

  • the provided null_buffer is not the same length as the offsets_buffer.
