Struct FixedColumn 

pub struct FixedColumn<'a, T: FixedWidth> { /* private fields */ }

Borrowed view over a packed little-endian array of T.

Implementations

impl<'a, T: FixedWidth> FixedColumn<'a, T>

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn validity(&self) -> Validity<'a>

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

pub fn raw(&self) -> &'a [u8]

Raw little-endian bytes for the entire column. len() * T::SIZE long.

pub fn value(&self, row: usize) -> T

Decode the value at row. Caller should consult is_null separately; this returns the underlying bit-pattern regardless.

Panics

Panics if row >= self.len(). #[track_caller] makes the panic point at the offending call site rather than into this accessor.

pub fn iter(&self) -> FixedIter<'_, 'a, T>

Iterator yielding Option<T> (None for null rows).

Trait Implementations

impl<'a, T: Clone + FixedWidth> Clone for FixedColumn<'a, T>

fn clone(&self) -> FixedColumn<'a, T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a, T: Copy + FixedWidth> Copy for FixedColumn<'a, T>

impl<'a, T: Debug + FixedWidth> Debug for FixedColumn<'a, T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
