Struct endbasic_std::testutils::MockConsole

pub struct MockConsole { /* fields omitted */ }

A console that supplies golden input and captures all output.

Implementations

impl MockConsole

pub fn add_input_chars(&mut self, s: &str)

Adds a bunch of characters as golden input keys.

Note that some escape characters within s are interpreted and added as their corresponding Keys for simplicity.

pub fn add_input_keys(&mut self, keys: &[Key])

Adds a bunch of keys as golden input.

pub fn captured_out(&self) -> &[CapturedOut]

Obtains a reference to the captured output.

pub fn set_size(&mut self, size: Position)

Sets the size of the mock console.

Trait Implementations

impl Console for MockConsole

fn clear(&mut self, how: ClearType) -> Result<()>

Clears the part of the console given by how.

fn color(&mut self, fg: Option<u8>, bg: Option<u8>) -> Result<()>

Sets the console's foreground and background colors to fg and bg.

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

Enters the alternate console.

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

Hides the cursor.

fn is_interactive(&self) -> bool

Returns true if the console is attached to an interactive terminal. This controls whether reading a line echoes back user input, for example.

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

Leaves the alternate console.

fn locate(&mut self, pos: Position) -> Result<()>

Moves the cursor to the given position, which must be within the screen.

fn move_within_line(&mut self, off: i16) -> Result<()>

Moves the cursor within the line. Positive values move right, negative values move left.

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

Writes text to the console, followed by a newline or CRLF pair depending on the needs of the console to advance a line.

fn read_key<'life0, 'async_trait>(
    &'life0 mut self
) -> Pin<Box<dyn Future<Output = Result<Key>> + 'async_trait>> where
    'life0: 'async_trait,
    Self: 'async_trait, 

Waits for and returns the next key press.

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

Shows the cursor.

fn size(&self) -> Result<Position>

Queries the size of the console.

fn write(&mut self, bytes: &[u8]) -> Result<()>

Writes the raw bytes into the console.

impl Default for MockConsole

fn default() -> Self

Returns the "default value" for a type.

impl Drop for MockConsole

fn drop(&mut self)

Executes the destructor for this type.
