Run an action with shared, read-only access to the current contents.

pub fn contents(&self) -> PromptContents

A snapshot of the current contents.

pub fn set_contents(&self, new_contents: PromptContents)

Replace all prompt content (the baseline).

pub fn apply(&self, overrides: impl FnOnce(&mut PromptContents))

pub fn set(&self, segment: PromptSegment, content: impl Into<Arc<str>>)

Push an override for a single segment and request an in-place repaint.

pub fn set_repainter(&self, new_repainter: Option<Arc<dyn Fn() + Send + Sync>>)

Install or remove the line editor’s repainter mechanism.
