Struct TestBackend 

pub struct TestBackend { /* private fields */ }

In-memory terminal backend for testing.

All output is captured in a buffer that can be inspected.

Implementations

impl TestBackend

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

Create a new test backend with the given size.

pub fn buffer(&self) -> &[u8]

Get the bytes written to this backend.

pub fn clear_buffer(&mut self)

Clear the output buffer.

pub fn is_raw_mode(&self) -> bool

Check if raw mode is active.

pub fn is_mouse_enabled(&self) -> bool

Check if mouse capture is active.

pub fn set_size(&mut self, width: u16, height: u16)

Set the terminal size (simulates a resize).

Trait Implementations

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

Enter raw mode (disable line buffering, echo, etc.).

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

Exit raw mode (restore normal terminal state).

fn write_raw(&mut self, data: &[u8]) -> Result<()>

Write raw bytes to the terminal.

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