Struct liner::History
[−]
[src]
pub struct History {
pub buffers: VecDeque<Buffer>,
// some fields omitted
}Structure encapsulating command history
Fields
buffers: VecDeque<Buffer>
Vector of buffers to store history in
Methods
impl History[src]
fn new() -> History
Create new History structure.
fn len(&self) -> usize
Number of items in history.
fn push(&mut self, new_item: Buffer) -> Result<()>
Add a command to the history buffer and remove the oldest commands when the max history size has been met. If writing to the disk is enabled, this function will be used for logging history to the designated history file.
fn file_name(&self) -> Option<&str>
Get the history file name.
fn set_file_name(&mut self, name: Option<String>)
Set history file name. At the same time enable history.
fn set_max_size(&mut self, size: usize)
Set maximal number of buffers stored in memory
fn set_max_file_size(&mut self, size: usize)
Set maximal number of entries in history file
fn load_history(&mut self) -> Result<()>
Load history from given file name
