Struct HostedCapabilities 

pub struct HostedCapabilities {
    pub web_search: bool,
}

The set of hosted capabilities that the provider advertises.

Distinguished from Capabilities:

• Capabilities describes model-level abilities (thinking, vision, tool_calls, etc.)
• HostedCapabilities describes the provider adapter’s own implementation state: whether the current adapter can declare hosted web_search, fetch, or code_execution on the wire.

At session startup, this struct is obtained via super::LlmProvider::hosted_capabilities and, together with capabilities.web_search.mode, determines the source of web search capability for the session. Note that local grep/glob tools (the search tool) are not part of the capability layer and are managed separately by [tools.search].

Native metadata returned by the model after a completions call.

Fields

web_search: bool

Whether the provider adapter supports hosted web search.

The hosted tool version is hardcoded internally by the adapter to always use the latest (Anthropic web_search_20260209, OpenAI Responses API web_search); the agent is unaware of the specific version field.

Implementations

impl HostedCapabilities

pub const fn with_web_search(web_search: bool) -> HostedCapabilities

Constructs from a single field. A convenience entry point for cross-crate tests and adapter implementations.

Trait Implementations

impl Clone for HostedCapabilities

fn clone(&self) -> HostedCapabilities

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for HostedCapabilities

impl Debug for HostedCapabilities

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

Formats the value using the given formatter.

impl Default for HostedCapabilities

fn default() -> HostedCapabilities

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for HostedCapabilities

fn deserialize<__D>( __deserializer: __D, ) -> Result<HostedCapabilities, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for HostedCapabilities

impl PartialEq for HostedCapabilities

fn eq(&self, other: &HostedCapabilities) -> 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 HostedCapabilities

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
