Struct FocusChain 

pub struct FocusChain {
    pub targets: Vec<FocusTarget>,
    pub active_index: Option<usize>,
}

Ordered focus targets with wrapping traversal and disabled-item skipping.

Fields

targets: Vec<FocusTarget>

active_index: Option<usize>

Implementations

impl FocusChain

pub fn new(targets: impl IntoIterator<Item = FocusTarget>) -> Self

pub fn active(&self) -> Option<&FocusTarget>

pub fn active_id(&self) -> Option<&str>

pub fn set_active(&mut self, id: &str) -> bool

pub fn move_focus(&mut self, direction: FocusDirection) -> Option<&FocusTarget>

Trait Implementations

impl Clone for FocusChain

fn clone(&self) -> FocusChain

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FocusChain

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

Formats the value using the given formatter.

impl Default for FocusChain

fn default() -> FocusChain

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FocusChain

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for FocusChain

impl PartialEq for FocusChain

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for FocusChain

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
