Struct Decor 

pub struct Decor {
    pub sync: bool,
    pub title: Option<Title>,
    pub progress: bool,
    pub notify: Option<Notify>,
    pub graphics: bool,
}

Which decorations a terminal is known to read.

Data rather than a chain of ifs at each call site, and computed once: the environment does not change under a running process, and a decision taken per frame is a decision that can differ per frame.

Fields

sync: bool

Wrap frames in DEC 2026.

title: Option<Title>

How to set the window title and put it back, if this terminal can do both.

progress: bool

Report progress as OSC 9;4.

notify: Option<Notify>

How to raise a desktop notification, if this terminal can.

graphics: bool

Read the kitty graphics protocol — which is how the treemap pane gets on the screen.

A column of this table rather than a second one keyed on the same two environment variables, because two tables read from one environment are two tables that can disagree about which terminal this is. It is also the only decoration here that is cells rather than chrome, and it is here anyway for that reason: what decides it is the terminal’s identity, which is this table’s whole subject.

Absence is a refusal to guess, as everywhere else. The protocol does define a query for “do you read this”, and it is a round trip with no bound on the silence — the blocking probe this module exists to avoid. See super::treemap.

Implementations

impl Decor

pub fn detect() -> Self

What this process’s terminal reads, from the environment and nothing else.

pub fn silent() -> Self

Nothing at all: the front end that is not a terminal, and the tests that are about something else.

Trait Implementations

impl Clone for Decor

fn clone(&self) -> Decor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Decor

impl Debug for Decor

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

Formats the value using the given formatter.

impl Default for Decor

fn default() -> Decor

Returns the “default value” for a type.
