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§
Sourcepub fn new(config: HistoryConfig) -> Self
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.
Sourcepub fn enabled(&self) -> bool
pub fn enabled(&self) -> bool
Returns whether history capture is enabled for the current config.
Sourcepub fn recent_commands(&self) -> Vec<String>
pub fn recent_commands(&self) -> Vec<String>
Returns visible commands in oldest-to-newest order using the active shell scope.
Sourcepub fn recent_commands_for(&self, shell_prefix: Option<&str>) -> Vec<String>
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.
Sourcepub fn list_entries(&self) -> Vec<HistoryEntry>
pub fn list_entries(&self) -> Vec<HistoryEntry>
Returns visible history entries in oldest-to-newest order using the active shell scope.
Sourcepub fn list_entries_for(&self, shell_prefix: Option<&str>) -> Vec<HistoryEntry>
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.
Sourcepub fn prune(&self, keep: usize) -> Result<usize>
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.
Sourcepub fn prune_for(
&self,
keep: usize,
shell_prefix: Option<&str>,
) -> Result<usize>
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.
Sourcepub fn clear_scoped(&self) -> Result<usize>
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.
