SharedHistory

Struct SharedHistory 

Source
pub struct SharedHistory { /* private fields */ }
Expand description

Thread-safe facade over the REPL history store.

Listing helpers return entries in oldest-to-newest order. Mutating helpers such as prune and clear only touch entries visible in the chosen scope.

Implementations§

Source§

impl SharedHistory

Source

pub fn new(config: HistoryConfig) -> Self

Creates a shared history store from the provided configuration.

Persisted history loading is best-effort: unreadable files and malformed lines are ignored during initialization.

Source

pub fn enabled(&self) -> bool

Returns whether history capture is enabled for the current config.

Source

pub fn recent_commands(&self) -> Vec<String>

Returns visible commands in oldest-to-newest order using the active shell scope.

Source

pub fn recent_commands_for(&self, shell_prefix: Option<&str>) -> Vec<String>

Returns visible commands in oldest-to-newest order for the provided shell prefix.

Matching profile scope and exclusion patterns still apply. When a shell prefix is provided, the returned commands have that prefix stripped.

Source

pub fn list_entries(&self) -> Vec<HistoryEntry>

Returns visible history entries in oldest-to-newest order using the active shell scope.

Source

pub fn list_entries_for(&self, shell_prefix: Option<&str>) -> Vec<HistoryEntry>

Returns visible history entries in oldest-to-newest order for the provided shell prefix.

Source

pub fn prune(&self, keep: usize) -> Result<usize>

Removes the oldest visible entries, keeping at most keep entries in the active scope.

Returns the number of removed entries.

§Errors

Returns an error when the history lock is poisoned or when persisting the updated history file fails.

Source

pub fn prune_for( &self, keep: usize, shell_prefix: Option<&str>, ) -> Result<usize>

Removes the oldest visible entries for a specific shell scope, keeping at most keep.

Returns the number of removed entries.

§Errors

Returns an error when the history lock is poisoned or when persisting the updated history file fails.

Source

pub fn clear_scoped(&self) -> Result<usize>

Clears all entries visible in the current scope.

Returns the number of removed entries.

§Errors

Returns an error when the history lock is poisoned or when persisting the updated history file fails.

Source

pub fn clear_for(&self, shell_prefix: Option<&str>) -> Result<usize>

Clears all entries visible to the provided shell prefix.

Returns the number of removed entries.

§Errors

Returns an error when the history lock is poisoned or when persisting the updated history file fails.

Source

pub fn save_command_line(&self, command_line: &str) -> Result<()>

Saves one command line through the underlying reedline::History implementation.

§Errors

Returns an error when the history lock is poisoned or when the underlying history backend rejects or fails to persist the item.
