Enum ViewerWaitMode 

pub enum ViewerWaitMode {
    Blocking,
    NonBlocking,
}

Determines whether the viewer call blocks or returns immediately.

Examples

Blocking mode (default):

use html_view::{ViewerOptions, ViewerWaitMode};

let opts = ViewerOptions::inline_html("<h1>Hello</h1>");
assert_eq!(opts.wait, ViewerWaitMode::Blocking);

// This call will block until the window is closed
html_view::open(opts).unwrap();

Non-blocking mode:

use html_view::{ViewerOptions, ViewerWaitMode, ViewerResult};

let mut opts = ViewerOptions::inline_html("<h1>Hello</h1>");
opts.wait = ViewerWaitMode::NonBlocking;

match html_view::open(opts).unwrap() {
    ViewerResult::NonBlocking(handle) => {
        // Returns immediately, window is open in background
        println!("Window opened with ID: {}", handle.id);
    }
    _ => unreachable!(),
}

Variants

Blocking

Block until the viewer exits and return the exit status.

This is the default mode and suitable for most use cases. The function call will not return until the user closes the window or a timeout is reached.

NonBlocking

Return immediately with a handle to the running viewer process.

Use this mode when you need to:

• Continue working while the viewer is open
• Manage multiple viewers simultaneously
• Poll for window status
• Terminate the viewer programmatically

Trait Implementations

impl Clone for ViewerWaitMode

fn clone(&self) -> ViewerWaitMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ViewerWaitMode

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

Formats the value using the given formatter.

impl PartialEq for ViewerWaitMode

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