Enum ViewKeyResolveError

pub enum ViewKeyResolveError {
    Missing {
        key: String,
    },
    Duplicate {
        key: String,
        count: usize,
    },
}

Error resolving a view key (View::key) in the element tree.

The requested key is owned by the error so it remains useful after the tree borrow ends. Duplicate counts include all string/static keys equal to the requested text; numeric keys are never matched by this API.

Examples

use ailloli_ui_runtime::element::ViewKeyResolveError;
let error = ViewKeyResolveError::Missing { key: String::from("search") };
assert!(matches!(error, ViewKeyResolveError::Missing { key } if key == "search"));

Variants

Missing

No retained string/static key matched.

Fields

key: String

Requested key text.

Duplicate

More than one retained string/static key matched.

Fields

key: String

Requested key text.

count: usize

Number of matching retained elements; always at least two.

Trait Implementations

impl Clone for ViewKeyResolveError

fn clone(&self) -> ViewKeyResolveError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ViewKeyResolveError

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

Formats the value using the given formatter.

impl PartialEq for ViewKeyResolveError

fn eq(&self, other: &ViewKeyResolveError) -> 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.
