Struct Context 

pub struct Context { /* private fields */ }

Thread-safe key-value context shared across pipeline execution.

Stores arbitrary JSON values keyed by string names. Supports isolated clones for parallel branches and atomic update application.

Implementations

impl Context

pub fn new() -> Self

Create an empty context.

pub fn with_values(values: HashMap<String, Value>) -> Self

Create a context with initial values.

pub async fn set(&self, key: impl Into<String>, value: Value)

Set a value in the context.

pub async fn get(&self, key: &str) -> Option<Value>

Get a value from the context.

pub async fn get_str(&self, key: &str) -> Option<String>

Get a string value from the context.

pub async fn snapshot(&self) -> HashMap<String, Value>

Take a snapshot of the current context state.

pub async fn clone_isolated(&self) -> Self

Create an isolated clone for parallel branches.

Changes to the clone do not affect the original.

pub async fn apply_updates(&self, updates: &HashMap<String, Value>)

Apply a batch of updates atomically.

pub async fn contains_key(&self, key: &str) -> bool

Check if the context contains a key.

pub async fn len(&self) -> usize

Get the number of entries.

pub async fn is_empty(&self) -> bool

Check if the context is empty.

Trait Implementations

impl Clone for Context

fn clone(&self) -> Context

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Context

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

Formats the value using the given formatter.

impl Default for Context

fn default() -> Self

Returns the “default value” for a type.
