Struct InverseStencilMap 

pub struct InverseStencilMap { /* private fields */ }

Transpose of a single StencilTable.

affected_outputs maps a set of changed input indices to the sorted, unique set of output rows whose stencils reference any of them.

Implementations

impl InverseStencilMap

pub fn output_count(&self) -> usize

Number of output rows of the original table.

pub fn affected_outputs(&self, changed_inputs: &[u32]) -> Vec<u32>

Output rows affected by changing changed_inputs, sorted ascending with duplicates removed. Input indices that no output references (or that are out of range) contribute nothing.

Trait Implementations

impl Clone for InverseStencilMap

fn clone(&self) -> InverseStencilMap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InverseStencilMap

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

Formats the value using the given formatter.

impl<'a> From<&'a StencilTable> for InverseStencilMap

fn from(table: &'a StencilTable) -> Self

Build the inverse (transpose) of table in a single pass over its entries.
