Struct ToolCatalogEvent 

pub struct ToolCatalogEvent {
    pub source: String,
    pub added: Vec<String>,
    pub removed: Vec<String>,
    pub changed: Vec<String>,
}

A change notification for a dynamic tool catalog.

Dynamic executors, such as MCP-backed executors, use this to tell the agent loop that the model should see a refreshed tool list on the next provider request.

Fields

source: String

Stable source identifier for the catalog that changed.

added: Vec<String>

Tool names that became available.

removed: Vec<String>

Tool names that are no longer available.

changed: Vec<String>

Tool names whose schema, description, or metadata changed.

Implementations

impl ToolCatalogEvent

pub fn new(source: impl Into<String>) -> Self

Builds a catalog event with empty change sets.

pub fn for_each_name_mut(&mut self, f: impl FnMut(&mut String))

Applies f to every tool name in added, removed, and changed.

pub fn retain_names(&mut self, predicate: impl FnMut(&str) -> bool)

Retains only tool names that pass predicate in added, removed, and changed.

Trait Implementations

impl Clone for ToolCatalogEvent

fn clone(&self) -> ToolCatalogEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ToolCatalogEvent

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

Formats the value using the given formatter.

impl Default for ToolCatalogEvent

fn default() -> ToolCatalogEvent

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ToolCatalogEvent

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ToolCatalogEvent

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

impl Serialize for ToolCatalogEvent

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
