Struct CallToolResponse 

pub struct CallToolResponse { /* private fields */ }

Output of the tool-call dispatcher pipeline.

• Some(value) — this plugin handled the call; value is the tool’s response (returned to the MCP client as the tool result).
• None — this plugin did not handle the call. yeti-mcp continues iterating the chain; if every registered plugin returns None, the host falls through to its built-in auto-inventory dispatcher.

Wrapped in a transparent newtype so the inner Option<String> can carry the bincode-safe JSON-text wire encoding of the Value (see ToolDefinition::input_schema for why bincode can’t ride a serde_json::Value directly). CallToolResponse::some / CallToolResponse::none / CallToolResponse::value are the construction / read helpers.

Implementations

impl CallToolResponse

pub const fn none() -> Self

Ok(None) equivalent — the plugin did not handle the call. Yeti-mcp falls through to the next service / auto-inventory.

pub fn some(value: &Value) -> Self

Wrap a Value for the wire. Equivalent to Some(value) — the plugin handled the call and value is the tool’s response.

pub fn value(&self) -> Option<Value>

Parse the wire form back into the typed Option<Value> the host’s dispatcher consumes. Decoding errors flatten to None so a malformed plugin response degrades to “not handled” rather than poisoning the chain.

pub const fn is_some(&self) -> bool

True if this response carries a plugin-supplied value (i.e. Some(...)).

pub const fn is_none(&self) -> bool

True if this response is the no-op fall-through (None).
