Struct AnsiCodeTracker 

pub struct AnsiCodeTracker {
    pub bold: bool,
    pub italic: bool,
    pub underline: bool,
    pub fg_color: Option<String>,
    pub bg_color: Option<String>,
    pub hyperlink: Option<ActiveHyperlink>,
}

Tracks active ANSI SGR and OSC 8 state across line breaks.

When wrapping styled text, styles must be closed at the end of each physical line and reopened at the start of the next. This struct records which attributes are currently active and can emit the corresponding escape sequences.

Example

use photon_ui::utils::AnsiCodeTracker;

let mut tracker = AnsiCodeTracker::new();
tracker.process("\x1b[1m"); // bold on
tracker.process("\x1b[31m"); // red fg
assert_eq!(tracker.current_codes(), "\x1b[1;31m");

Fields

bold: bool

Bold (SGR 1) is active.

italic: bool

Italic (SGR 3) is active.

underline: bool

Underline (SGR 4) is active.

fg_color: Option<String>

Active foreground color SGR parameter, e.g. "31" or "38;5;240".

bg_color: Option<String>

Active background color SGR parameter, e.g. "41" or "48;5;240".

hyperlink: Option<ActiveHyperlink>

Active OSC 8 hyperlink, if any.

Implementations

impl AnsiCodeTracker

pub fn new() -> Self

Create a tracker with no active codes.

pub fn process(&mut self, seq: &str)

Process an ANSI escape sequence, updating internal state.

Supports:

• OSC 8 hyperlink open / close (\x1b]8;;URL\x1b\\, \x1b]8;;\x1b\\)
• SGR codes (\x1b[…m) for bold, italic, underline, and colors

pub fn current_codes(&self) -> String

Return the escape sequences needed to restore all active codes.

This is used to reopen styles at the beginning of a continuation line.

pub fn line_end_reset(&self) -> String

Return the escape sequences needed to close active codes at a line end.

Unlike a full SGR reset, this only closes attributes that would bleed into padding or subsequent lines (underline and hyperlinks). The caller is responsible for emitting \x1b[0m when a full SGR reset is needed.

pub fn has_active_codes(&self) -> bool

Returns true if any SGR or OSC 8 code is currently active.

Trait Implementations

impl Clone for AnsiCodeTracker

fn clone(&self) -> AnsiCodeTracker

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AnsiCodeTracker

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

Formats the value using the given formatter.

impl Default for AnsiCodeTracker

fn default() -> AnsiCodeTracker

Returns the “default value” for a type.

impl PartialEq for AnsiCodeTracker

fn eq(&self, other: &AnsiCodeTracker) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
