Struct PromptHistory 

pub struct PromptHistory { /* private fields */ }

A persisted, searchable prompt history.

Implementations

impl PromptHistory

pub fn new() -> PromptHistory

An empty history (no file backing yet).

pub fn load_from_file(path: &Path) -> PromptHistory

Load from path’s one-escaped-prompt-per-line format. A missing file (first run) or an unreadable one is treated as “empty history” rather than an error — losing prompt history is never worth refusing to start the TUI over.

pub fn save_to_file(&self, path: &Path)

Persist to path (one escaped prompt per line, overwriting). Best-effort: a write failure (e.g. a read-only config dir) is silently dropped — the in-memory session history is unaffected either way, matching crate::permissions::ApprovalCache::approve’s “a lost write costs a feature, never a crash” precedent.

pub fn push(&mut self, entry: impl Into<String>)

Append one submitted prompt. Adjacent-duplicate suppression (the same prompt submitted twice in a row doesn’t grow the list) mirrors shell/readline history convention.

pub fn len(&self) -> usize

How many entries this history holds.

pub fn is_empty(&self) -> bool

Whether this history is empty.

pub fn search(&self, query: &str) -> Vec<&str>

All entries the substring query (case-insensitive) appears in, MOST RECENT first (Ctrl+R convention: typing narrows toward the latest matching prompt). Empty query returns everything, most recent first.
