Struct Checkpoint 

pub struct Checkpoint { /* private fields */ }

A checkpoint represents a saved state of the notebook

Contains all variables, functions, and execution state at a point in time.

Examples

use ruchy::notebook::persistence::Checkpoint;

let checkpoint = Checkpoint::new("initial_state".to_string());
assert_eq!(checkpoint.name(), "initial_state");
assert_eq!(checkpoint.variable_count(), 0);

Implementations

impl Checkpoint

pub fn new(name: String) -> Self

Create a new empty checkpoint

Examples

use ruchy::notebook::persistence::Checkpoint;

let checkpoint = Checkpoint::new("checkpoint1".to_string());
assert_eq!(checkpoint.name(), "checkpoint1");

pub fn with_state(name: String, state_data: HashMap<String, String>) -> Self

Create a checkpoint with state data

pub fn name(&self) -> &str

Get the checkpoint name

pub fn state_data(&self) -> &HashMap<String, String>

Get the state data

pub fn variable_count(&self) -> usize

Get number of variables in checkpoint

pub fn has_variable(&self, name: &str) -> bool

Check if checkpoint has a specific variable

pub fn get_variable(&self, name: &str) -> Option<&String>

Get variable value from checkpoint

pub fn timestamp(&self) -> SystemTime

Get timestamp

pub fn is_empty(&self) -> bool

Check if checkpoint is empty

Trait Implementations

impl Clone for Checkpoint

fn clone(&self) -> Checkpoint

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Checkpoint

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Checkpoint

fn eq(&self, other: &Checkpoint) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
