Struct TerminalModel 

pub struct TerminalModel { /* private fields */ }

A minimal terminal model for testing presenter output.

Tracks grid state, cursor position, SGR state, and hyperlinks. Processes a subset of ANSI sequences that we emit.

Implementations

impl TerminalModel

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

Create a new terminal model with the given dimensions.

Dimensions are clamped to a minimum of 1×1 to prevent arithmetic underflows in cursor-positioning and diff helpers.

pub fn width(&self) -> usize

Get the terminal width.

pub fn height(&self) -> usize

Get the terminal height.

pub fn cursor(&self) -> (usize, usize)

Get the cursor position as (x, y).

pub fn sgr_state(&self) -> &SgrState

Get the current SGR state.

pub fn modes(&self) -> &ModeFlags

Get the current mode flags.

pub fn cell(&self, x: usize, y: usize) -> Option<&ModelCell>

Get the cell at (x, y). Returns None if out of bounds.

pub fn current_cell(&self) -> Option<&ModelCell>

Get the current cell under the cursor.

pub fn cells(&self) -> &[ModelCell]

Get all cells as a slice.

pub fn row(&self, y: usize) -> Option<&[ModelCell]>

Get a row of cells.

pub fn row_text(&self, y: usize) -> Option<String>

Extract the text content of a row as a string (trimmed of trailing spaces).

pub fn link_url(&self, link_id: u32) -> Option<&str>

Get the URL for a link ID.

pub fn has_dangling_link(&self) -> bool

Check if the terminal has a dangling hyperlink (active link after processing).

pub fn sync_output_balanced(&self) -> bool

Check if synchronized output is properly balanced.

pub fn reset(&mut self)

Reset the terminal model to initial state.

pub fn process(&mut self, bytes: &[u8])

Process a byte sequence, updating the terminal state.

pub fn diff_grid(&self, expected: &[ModelCell]) -> Option<String>

Compare two grids and return a diff description for debugging.

pub fn dump_sequences(bytes: &[u8]) -> String

Dump the escape sequences in a human-readable format (for debugging test failures).

Trait Implementations

impl Debug for TerminalModel

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

Formats the value using the given formatter.
