Struct Table 

pub struct Table { /* private fields */ }

Explicit offsets along one axis, with Steps::FILL where a fill goes: a list of offsets, or index values that each give one. start and len choose the offsets in use, so that slicing a table copies none of them.

Implementations

impl Table

pub fn new(offsets: Vec<usize>) -> Table

A table of offsets.

pub fn indices( values: Arc<dyn IndexSource>, size: usize, even: Option<(usize, isize)>, ) -> Table

A table that reads values as positions along an axis of size positions. A negative value counts back from the end. Every value must lie within the axis, as structure::index_table checks. even gives the first position and the step between positions, where they’re evenly spaced.

pub fn len(&self) -> usize

The number of offsets.

pub fn listed(&self) -> Option<&[usize]>

The listed offsets in use, or None where the table converts index values as it reads them.

pub fn get(&self, j: usize) -> Option<usize>

Offset j, or None for a fill.

pub fn chunks(&self, each: impl FnMut(usize, &[usize]))

Calls each with the position of each run of offsets and the run, in order: the listed offsets as one run, or index values converted into runs of up to TABLE_CHUNK offsets.

pub fn all(&self, f: impl FnMut(Option<usize>) -> bool) -> bool

Whether f holds for every offset, None for a fill. It stops at the first offset that fails, and converts no index values after it.

pub fn slice(&self, start: usize, len: usize) -> Table

Offsets start..start + len of this table.

pub fn scaled(self, k: usize) -> Table

This table with its offsets k times as far apart. A plan scales a table of listed offsets while it owns them alone, so this multiplies them in place. Index values keep their scale beside them.

pub fn fills(&self) -> bool

Whether some offset is a fill. Index values give none.

Trait Implementations

impl Clone for Table

fn clone(&self) -> Table

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Table

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

Formats the value using the given formatter.

impl Eq for Table

impl PartialEq for Table

fn eq(&self, other: &Table) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
