Struct CharSet 

pub struct CharSet { /* private fields */ }

Ordered sequence of characters a split-flap tile can display.

Order determines which intermediate characters appear during a Sequential or Combined flip animation. Distance always travels forward (wraps around), never backward.

Implementations

impl CharSet

pub fn new(chars: impl Into<Arc<[char]>>) -> Result<Self, CharSetError>

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

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

O(1) lookup by index.

pub fn index_of(&self, ch: char) -> Option<usize>

O(1) index lookup for a character. Returns None if not in set.

pub fn contains(&self, ch: char) -> bool

pub fn distance(&self, from: char, to: char) -> usize

Forward-wrapping distance. Unknown characters resolve to index 0.

Trait Implementations

impl Clone for CharSet

fn clone(&self) -> CharSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CharSet

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

Formats the value using the given formatter.

impl Default for CharSet

fn default() -> Self

Returns the “default value” for a type.
