Struct Mapping 

pub struct Mapping { /* private fields */ }

A composable pipeline of StepMaps, with optional mirror links so a position can be recovered when mapped through a map and its mirror.

Implementations

impl Mapping

pub fn new() -> Self

An empty mapping.

pub fn len(&self) -> usize

Number of maps in the pipeline.

pub fn is_empty(&self) -> bool

Whether the pipeline is empty.

pub fn maps(&self) -> &[StepMap]

The maps, in order.

pub fn append_map(&mut self, map: StepMap)

Append a map to the pipeline.

pub fn append_map_mirrored(&mut self, map: StepMap, mirrors: usize)

Append map, mirrored against the existing map at index mirrors.

pub fn map(&self, pos: usize, assoc: i32) -> usize

Map pos through the whole pipeline.

pub fn map_result(&self, pos: usize, assoc: i32) -> MapResult

Map pos, skipping across mirrored map pairs via recovery so a position survives a step followed by its inverse.

Trait Implementations

impl Clone for Mapping

fn clone(&self) -> Mapping

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mapping

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

Formats the value using the given formatter.

impl Default for Mapping

fn default() -> Mapping

Returns the “default value” for a type.
