Struct DcpContext 

pub struct DcpContext { /* private fields */ }

Memory-mapped context for zero-copy sharing

Implementations

impl DcpContext

pub const MIN_SIZE: usize = ContextLayout::SIZE

Minimum buffer size

pub fn new(conversation_id: u64) -> Self

Create a new context with the given conversation ID

pub fn from_shared(buffer: Box<[u8]>) -> Result<Self, DCPError>

Create a context from existing shared memory

pub fn as_bytes(&self) -> &[u8]

Get the raw buffer for sharing

pub fn size(&self) -> usize

Get the buffer size

pub fn conversation_id(&self) -> u64

Get the conversation ID

pub fn message_count(&self) -> u64

Get the message count (atomic read)

pub fn increment_message_count(&self) -> u64

Increment the message count atomically

pub fn get_tool_state(&self, index: usize) -> Option<&ToolState>

Zero-copy access to tool state by index

pub fn find_tool_state(&self, tool_id: u32) -> Option<&ToolState>

Find tool state by tool_id

pub fn update_tool_state( &mut self, index: usize, state: &ToolState, ) -> Result<(), DCPError>

Atomic update with memory fence

Safety

This function uses unsafe pointer operations but ensures memory safety through proper bounds checking and memory fencing.

pub fn set_tool_state(&mut self, state: &ToolState) -> Result<usize, DCPError>

Update tool state by tool_id, finding or allocating a slot

pub fn clear_tool_state(&mut self, index: usize) -> Result<(), DCPError>

Clear a tool state slot

pub fn version(&self) -> u32

Get the version
