Enum Target 

pub enum Target {
    Display(usize),
    WindowTitled(String),
}

What to capture: a display by index, or a window matched by exact title.

Construction is infallible — a matching window need not exist yet (it may appear later and reattach). Resolution failure surfaces at capture time as CaptureError::TargetNotFound.

Variants

Display(usize)

The Nth display reported by the platform (0 = first).

WindowTitled(String)

The first window whose title matches exactly.

Implementations

impl Target

pub fn display(index: usize) -> Self

Capture the display at index (0 = first).

pub fn window_titled(title: impl Into<String>) -> Self

Capture the first window whose title exactly equals title.

Trait Implementations

impl Clone for Target

fn clone(&self) -> Target

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Target

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

Formats the value using the given formatter.

impl Eq for Target

impl PartialEq for Target

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