Struct Ctx 

pub struct Ctx { /* private fields */ }

Execution context shared across all agents in a workflow.

Ctx carries two things:

• a string key-value store for cross-agent data,
• an append-only event log for diagnostic messages.

State is not reset between crate::Runner::run calls, so the store and log accumulate across runs unless cleared explicitly with clear_logs or clear.

LLM access lives on crate::LlmConfig, not on Ctx. Agents that need an LLM hold their own crate::LlmConfig and call crate::LlmConfig::request to start a chat request.

Implementations

impl Ctx

pub fn new() -> Self

Create a new empty context (KV store and event log).

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

Insert or overwrite a key in the KV store.

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

Look up a key in the KV store.

pub fn remove(&mut self, key: &str) -> Option<String>

Remove a key from the KV store, returning its value if it existed.

pub fn log(&mut self, msg: impl Into<String>)

Append a message to the event log.

pub fn logs(&self) -> &[String]

Return all log messages in order.

pub fn clear_logs(&mut self)

Clear the event log, leaving the KV store intact.

pub fn clear(&mut self)

Clear both the KV store and the event log.

Trait Implementations

impl Default for Ctx

fn default() -> Self

Returns the “default value” for a type.
