Struct OptionsRef 

pub struct OptionsRef<'g> { /* private fields */ }

Read-only iterator over the options of a Node.

Implementations

impl<'g> OptionsRef<'g>

pub fn get(&self, play: Move) -> Option<PlayRef<'g>>

pub fn contains(&self, play: Move) -> bool

pub fn position(&self) -> Position

pub fn get_index(&self, index: usize) -> Option<PlayRef<'g>>

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

pub const fn mode(&self) -> Mode

pub fn state(&self) -> &State

pub fn legal(&self) -> &[Move]

pub fn first(&self) -> Option<PlayRef<'g>>

pub fn after_first(&self) -> OptionsRef<'g>

pub fn split_first(&self) -> Option<(PlayRef<'g>, OptionsRef<'g>)>

Combines Self::first and Self::after_first.

When this contains all options after a move, the first option is the mainline move, and the remaining options are variations from the same position.

pub fn iter(self) -> OptionsIter<'g>
