Implementations

impl U64ColumnRef<'_>

pub fn try_from_array(array: &dyn Array) -> Option<U64ColumnRef<'_>>

Returns a compatible unsigned 64-bit view for array.

pub fn len(&self) -> usize

Returns the number of values in the column.

pub fn is_empty(&self) -> bool

Returns whether the column has no values.

pub fn is_null(&self, i: usize) -> bool

Returns whether the value at row i is null.

pub fn value(&self, i: usize) -> Option<u64>

Returns the value at row i, or None when a signed representation is negative.
