Type Alias TransientContext 

pub type TransientContext = TransientContext;

Aliased Type

pub struct TransientContext {
    pub major_mode: Option<String>,
    pub minor_modes: Vec<String>,
    pub buffer: Option<u32>,
    pub args: Args,
}

Fields

major_mode: Option<String>

The active major’s id, if the buffer has one. Emacs magit’s :if-mode question.

minor_modes: Vec<String>

The active minor ids — the looser :if-derived family test. A separate field from major-mode on purpose: a flat list of active mode ids can only answer one of the two questions.

buffer: Option<u32>

The buffer the menu was opened over. none mid-boot, where a builder degrades exactly as it does for the mode fields.

args: Args

TR.3a: the arguments the open carried (effect::open-transient’s payload).

This is what lets a menu DRILL DOWN: org’s capture menu has a row per template, and the fields menu that row opens needs to know which template it is collecting for. The alternative is guest memory, which <Esc> never clears — the next open would inherit the last one’s subject.
