Returns an error if value has different precision, scale or length in bytes than this builder

pub fn append_null(&mut self)

Append a null value to the array.

pub fn append_option(&mut self, value: Option<&Decimal256>) -> Result<()>

Appends an Option<&Decimal256> into the builder.

pub fn finish(&mut self) -> Decimal256Array
