Module render 

Structs

RenderOpts

RenderState

Per-source rendering state that persists across line renders. Carries the SGR style register and the current OSC 8 hyperlink so that an unclosed \x1b[31m on line N keeps line N+1 red until reset.

Enums

AnsiMode

How the renderer treats escape sequences in input bytes.

Cell

TrueColor

Whether the writer should pass 24-bit RGB colors through to the terminal or downsample to the 256-color cube first. Resolved once at startup.

Functions

color_256_to_rgb

Inverse of the relevant range of rgb_to_256: the RGB triple for an xterm 256-color index in the 6×6×6 cube (16..=231) or the grayscale ramp (232..=255). Indices 0..=15 (terminal-defined) are not produced by rgb_to_256; we map them to black defensively.

count_rows

display_width

Full expanded display width of a line in columns (tabs expanded to tab stops, cluster widths summed). Used by the viewport to clamp horizontal scroll. Independent of cols/left_col.

next_tab_stop

Next tab stop strictly greater than col, honoring explicit tab_stops (with last-interval repetition past the final stop) or uniform width.

render_line

rgb_to_256

Downsample 24-bit RGB to the xterm 256-color palette. Uses the standard 6×6×6 cube plus the 24-step grayscale ramp.
