Struct FakeClipboard 

pub struct FakeClipboard { /* private fields */ }

In-memory Clipboard for tests / headless CI and the default boot binding before a real backend is installed (CB.2 / CB.4). Thread-safe; round-trips text without touching any OS resource.

Examples

use lattice_core::{Clipboard, ClipboardHandle, FakeClipboard};
use std::sync::Arc;

let clip: ClipboardHandle = Arc::new(FakeClipboard::new());
assert_eq!(clip.read(), None); // starts empty
clip.write("yanked".to_string());
assert_eq!(clip.read().as_deref(), Some("yanked"));

Implementations

impl FakeClipboard

pub fn new() -> Self

An empty clipboard: Clipboard::read returns None until the first write.

Trait Implementations

impl Clipboard for FakeClipboard

fn read(&self) -> Option<String>

Read the clipboard’s current text. None when the clipboard is empty, holds non-text content, or the backend can’t read (e.g. OSC52 over SSH, where read-back is unsupported — the register layer falls back to its in-memory entry). Only called from a spawn_blocking context.

fn write(&self, text: String)

Write text to the clipboard. Fire-and-forget: never blocks the caller. A backend whose write would block spawns its own blocking task.

impl Debug for FakeClipboard

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

Formats the value using the given formatter.

impl Default for FakeClipboard

fn default() -> FakeClipboard

Returns the “default value” for a type.
