Struct Hit 

pub struct Hit {
    pub role: HitRole,
    pub target: Option<Expr>,
    pub detail: Vec<(String, Expr)>,
}

A hit-test result: what was under the pointer, the runtime value it stands for, and any role-specific detail (for example a port’s node/port/dir).

Fields

role: HitRole

The kind of element hit.

target: Option<Expr>

The runtime value the element represents, if any.

detail: Vec<(String, Expr)>

Role-specific fields (control name, port descriptor, field path, …).

Implementations

impl Hit

pub fn blank() -> Self

A blank-background hit.

pub fn on(role: HitRole, target: Expr) -> Self

A hit on role standing for target.

pub fn with(self, key: &str, value: Expr) -> Self

Attach a role-specific detail field.

Trait Implementations

impl Clone for Hit

fn clone(&self) -> Hit

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Hit

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

Formats the value using the given formatter.

impl Eq for Hit

impl PartialEq for Hit

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