Struct ElementId 

pub struct ElementId(pub u32);

Interned, process-stable index for a registered theme element. Allocated at registration; the hot-path read is resolved.get(id) — an array index, no string hashing.

Tuple Fields

0: u32

Implementations

impl ElementId

pub const INVALID: ElementId

Out-of-range sentinel. ResolvedTheme::get(INVALID) returns Style::empty() (out-of-range ids are styleless, never a panic), so it is the safe default + not-found fallback for the id-capture helpers (crate::BuiltinElementIds).

Trait Implementations

impl Clone for ElementId

fn clone(&self) -> ElementId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ElementId

impl Debug for ElementId

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

Formats the value using the given formatter.

impl Eq for ElementId

impl Hash for ElementId

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ElementId

fn cmp(&self, other: &ElementId) -> 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 ElementId

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for ElementId

fn partial_cmp(&self, other: &ElementId) -> 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.
