pub struct AnnotationColumn<T> { /* private fields */ }

One immutable typed annotation column with three-state validity.

Implementations

impl<T> AnnotationColumn<T>

pub fn from_values(values: Vec<T>) -> Result<Self, CapacityError>

Builds an all-present column.

Errors

Returns CapacityError when the column exceeds the supported row count.

pub fn len(&self) -> u32

Number of atom rows covered by the column.

pub fn is_empty(&self) -> bool

Returns true when the column covers no rows.

pub fn presence(&self, atom: u32) -> Presence

Validity state at one atom row.

pub fn values(&self) -> &[T]

Dense values backing this column.

impl<T> AnnotationColumn<T>

pub fn from_entries( entries: impl IntoIterator<Item = (T, Presence)>, ) -> Result<Self, CapacityError>

Builds a column from dense values paired with their validity state.

Errors

Returns CapacityError when the column exceeds the supported row count.

impl<T: Copy> AnnotationColumn<T>

pub fn get(&self, atom: u32) -> Option<(T, Presence)>

Value and validity at one row, or None outside the column.
