Struct ObjectStates 

pub struct ObjectStates(/* private fields */);

LVGL-like object state bits.

The default state is represented by no bits set. Style resolution consumes these bits in later LPAR phases; this module only stores and queries them.

Implementations

impl ObjectStates

pub const DEFAULT: Self

No state bits set.

pub const DISABLED: Self

Disabled state for style selection.

pub const FOCUSED: Self

Focused state for style selection and focus bookkeeping.

pub const PRESSED: Self

Pressed state for pointer or key activation.

pub const CHECKED: Self

Checked state for toggleable controls.

pub const EDITED: Self

Edited state for text or value editing modes.

pub const fn from_bits_truncate(bits: u32) -> Self

Return a state set from raw bits, dropping unknown bits.

pub const fn bits(self) -> u32

Return the raw state bits.

pub const fn contains(self, other: Self) -> bool

Return true when all state bits in other are set.

pub fn insert(&mut self, other: Self)

Insert all state bits in other.

pub fn remove(&mut self, other: Self)

Remove all state bits in other.

pub fn set(&mut self, other: Self, enabled: bool)

Set or clear all state bits in other.
