Struct TerminalMetrics 

pub struct TerminalMetrics {
    pub cell_width: f32,
    pub cell_height: f32,
    pub columns: u16,
    pub rows: u16,
}

Terminal display metrics shared between rendering and input systems

This provides the coordinate conversion information needed by:

• Mouse input handlers (screen to grid coordinate conversion)
• Text rendering systems (grid to screen coordinate conversion)
• Selection and UI overlays (coordinate mapping)

This type can be used as a Bevy Resource when the bevy feature is enabled.

Fields

cell_width: f32

Width of a single character cell in pixels

cell_height: f32

Height of a single character cell in pixels

columns: u16

Number of columns in the terminal grid

rows: u16

Number of rows in the terminal grid

Implementations

impl TerminalMetrics

pub fn new( font_size: f32, line_height_multiplier: f32, columns: u16, rows: u16, ) -> Self

Create metrics from font size and terminal dimensions

pub fn screen_to_grid(&self, screen_x: f32, screen_y: f32) -> (u16, u16)

Convert screen coordinates to grid coordinates

Arguments

• screen_x - X coordinate in pixels (from left edge)
• screen_y - Y coordinate in pixels (from top edge, Y-down)

Returns

Grid position clamped to valid bounds (col, row)

pub fn grid_to_screen(&self, col: u16, row: u16) -> (f32, f32)

Convert grid coordinates to screen coordinates (top-left of cell)

Returns

Screen position in pixels (x, y)

pub fn screen_size(&self) -> (f32, f32)

Get total terminal size in pixels
