Enum HostResolveError 

pub enum HostResolveError {
    NotFound,
    EmptyMatchedFrame,
    UnknownAppFrame,
    CentroidOutOfFrame {
        nx: f64,
        ny: f64,
    },
}

Errors returned by resolve_to_norm_coord.

Variants

NotFound

The selector matched no node in the tree (after visibility filter).

EmptyMatchedFrame

Matched node has empty bounds (w*h == 0); element is offscreen or hidden.

UnknownAppFrame

Tree bounds (tree.bounds) have w/h ≤ 0 — unknown app frame, cannot normalize.

CentroidOutOfFrame

Computed (nx, ny) is outside the open interval (0, 1) — matched node centroid is offscreen.

Fields

nx: f64

Normalized x coordinate (would-be tap target).

ny: f64

Normalized y coordinate (would-be tap target).

Trait Implementations

impl Debug for HostResolveError

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

Formats the value using the given formatter.

impl Display for HostResolveError

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

impl Error for HostResolveError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for HostResolveError

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

Equality operator ==.

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