Struct AgentContextManager 

pub struct AgentContextManager { /* private fields */ }

Agent Context Manager

Manages the lifecycle of agent contexts including:

• Creating new contexts with unique IDs
• Inheriting context from parent agents
• Compressing contexts to reduce token usage
• Filtering sensitive data
• Merging multiple contexts
• Persisting and loading contexts

Implementations

impl AgentContextManager

pub fn new() -> Self

Create a new context manager with default storage directory

pub fn with_storage_dir(storage_dir: impl Into<PathBuf>) -> Self

Create a new context manager with a custom storage directory

pub fn create_context( &mut self, parent: Option<&AgentContext>, config: Option<ContextInheritanceConfig>, ) -> AgentContext

Create a new agent context, optionally inheriting from a parent

pub fn inherit( &self, parent: &AgentContext, config: &ContextInheritanceConfig, ) -> AgentContext

Inherit context from a parent based on configuration

pub fn compress( &self, context: &mut AgentContext, target_tokens: usize, ) -> AgentContextResult<CompressionResult>

Compress a context to reduce token count

This method reduces the context size by:

1. Summarizing older conversation messages
2. Removing older file contexts
3. Removing older tool results

pub fn filter( &self, context: &AgentContext, filter: &ContextFilter, ) -> AgentContext

Filter sensitive data from a context

pub fn merge(&self, contexts: Vec<&AgentContext>) -> AgentContext

Merge multiple contexts into one

pub fn get_context(&self, context_id: &str) -> Option<&AgentContext>

Get a context by ID

pub fn get_context_mut(&mut self, context_id: &str) -> Option<&mut AgentContext>

Get a mutable context by ID

pub fn update_context( &mut self, context_id: &str, updates: ContextUpdate, ) -> AgentContextResult<()>

Update a context with the given updates

pub fn delete_context(&mut self, context_id: &str) -> bool

Delete a context by ID

pub async fn persist_context( &self, context: &AgentContext, ) -> AgentContextResult<()>

Persist a context to disk

pub async fn load_context( &mut self, context_id: &str, ) -> AgentContextResult<Option<AgentContext>>

Load a context from disk

pub fn estimate_token_count(&self, context: &AgentContext) -> usize

Estimate token count for a context

This is a rough estimate based on character count. For more accurate counts, use a proper tokenizer.

pub fn update_token_count(&self, context: &mut AgentContext)

Update the token count in context metadata

pub fn list_context_ids(&self) -> Vec<String>

List all context IDs in memory

pub fn storage_dir(&self) -> &PathBuf

Get the storage directory path

Trait Implementations

impl Debug for AgentContextManager

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

Formats the value using the given formatter.

impl Default for AgentContextManager

fn default() -> Self

Returns the “default value” for a type.
