Struct TestBackend 

pub struct TestBackend {
    pub buffer: Buffer,
    pub lifecycle: Vec<&'static str>,
    pub clipboard: Vec<String>,
}

In-memory backend: applies flushed updates to a Buffer for assertions.

Fields

buffer: Buffer

lifecycle: Vec<&'static str>

clipboard: Vec<String>

Clipboard payloads received via copy_to_clipboard, oldest first.

Implementations

impl TestBackend

pub fn new(width: u16, height: u16) -> Self

pub fn to_text(&self) -> String

Trait Implementations

impl Backend for TestBackend

fn size(&self) -> Result<(u16, u16)>

Current size as (columns, rows).

fn enter(&mut self) -> Result<()>

Prepare the target for drawing. MUST leave the screen cleared: the first frame is diffed against an all-blank buffer.

fn leave(&mut self) -> Result<()>

Restore the target to its pre-enter state.

fn flush(&mut self, updates: &[CellUpdate]) -> Result<()>

Apply a batch of changed cells.

fn copy_to_clipboard(&mut self, text: &str) -> Result<()>

Set the system clipboard to text (OSC 52). Default is a no-op so backends without a real terminal (or apps that never copy) don’t pay for the support; best-effort — the terminal emulator may ignore the sequence.
