Enum PresenceIR 

#[non_exhaustive]
pub enum PresenceIR {
    Visible,
    Hidden,
    Inactive,
    Invisible,
    Unknown,
}

Visibility/presence state.

Mirrors the XFA presence attribute plus an explicit Unknown for snapshots taken before resolution.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Visible

Default; rendered.

Hidden

Hidden via presence="hidden".

Inactive

Inactive (not rendered, not data-bound).

Invisible

Invisible (skipped during rendering but still in the tree).

Unknown

Presence not determined yet at the snapshot point.

Implementations

impl PresenceIR

pub fn tag(self) -> &'static str

Stable string tag used in canonical JSON output.

Trait Implementations

impl Clone for PresenceIR

fn clone(&self) -> PresenceIR

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PresenceIR

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

Formats the value using the given formatter.

impl Default for PresenceIR

fn default() -> PresenceIR

Returns the “default value” for a type.

impl Ord for PresenceIR

fn cmp(&self, other: &PresenceIR) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PresenceIR

fn eq(&self, other: &PresenceIR) -> 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 PartialOrd for PresenceIR

fn partial_cmp(&self, other: &PresenceIR) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
