Enum McpEnvelope 

pub enum McpEnvelope {
    Request(McpRequest),
    Notification(McpNotification),
    Response(McpResponse),
    Error(McpErrorEnvelope),
}

One MCP JSON-RPC 2.0 envelope: the typed payload carried by a single frame.

The four variants are the complete envelope shapes the codec:mcp codec round-trips; any other JSON structure is rejected.

Variants

Request(McpRequest)

A method call with an id expecting a response.

Notification(McpNotification)

A method call without an id, expecting no response.

Response(McpResponse)

A successful result for a prior request id.

Error(McpErrorEnvelope)

A failure for a prior request id.

Trait Implementations

impl Clone for McpEnvelope

fn clone(&self) -> McpEnvelope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for McpEnvelope

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

Formats the value using the given formatter.

impl PartialEq for McpEnvelope

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