Struct ExecutionHistory 

pub struct ExecutionHistory {
    pub steps: VecDeque<ExecutionStep>,
    pub file_snapshots: HashMap<String, FileSnapshot>,
}

Execution history tracking.

Fields

steps: VecDeque<ExecutionStep>

All execution steps in order

file_snapshots: HashMap<String, FileSnapshot>

File snapshots for key files at checkpoint time

Implementations

impl ExecutionHistory

pub fn new() -> Self

Execution history must be bounded.

The historical unbounded add_step API is intentionally not available in non-test builds to avoid reintroducing unbounded growth.

use ralph_workflow::checkpoint::ExecutionHistory;
use ralph_workflow::checkpoint::execution_history::{ExecutionStep, StepOutcome};

let mut history = ExecutionHistory::new();
let step = ExecutionStep::new("Development", 0, "dev_run", StepOutcome::success(None, vec![]));

// Unbounded push is not part of the public API.
history.add_step(step);

Create a new execution history.

pub fn add_step_bounded(&mut self, step: ExecutionStep, limit: usize)

Add an execution step with explicit bounding (preferred method).

This is the preferred method that enforces bounded memory growth. Use this to prevent unbounded growth.

pub fn clone_bounded(&self, limit: usize) -> Self

Clone this execution history while enforcing a hard step limit.

This is intended for resume paths where a legacy checkpoint may contain an oversized steps buffer. Cloning only the tail avoids allocating memory proportional to the checkpoint’s full history.

Trait Implementations

impl Clone for ExecutionHistory

fn clone(&self) -> ExecutionHistory

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExecutionHistory

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

Formats the value using the given formatter.

impl Default for ExecutionHistory

fn default() -> ExecutionHistory

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ExecutionHistory

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ExecutionHistory

fn eq(&self, other: &ExecutionHistory) -> 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.

impl Serialize for ExecutionHistory

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
