Struct ToolCall 

pub struct ToolCall {
    pub tool_call_id: String,
    pub tool_name: String,
    pub input: Value,
    pub provider_executed: Option<bool>,
    pub dynamic: Option<bool>,
    pub thought_signature: Option<String>,
    pub provider_metadata: Option<ProviderMetadata>,
    pub invalid: Option<bool>,
    pub error: Option<AiMuxError>,
}

A tool call requested by the model.

Fields

tool_call_id: String

Provider-assigned call id.

tool_name: String

Tool name.

input: Value

Parsed arguments, or the original string when invalid is true and the provider input was not valid JSON.

provider_executed: Option<bool>

Whether the tool call will be executed by the provider.

dynamic: Option<bool>

Whether the tool is dynamic (defined at runtime, e.g. MCP tools).

thought_signature: Option<String>

Provider-assigned thought signature (e.g. Google Gemini thoughtSignature). Must be echoed back verbatim on the follow-up turn when the tool result is sent; thinking models reject the request otherwise.

provider_metadata: Option<ProviderMetadata>

Additional provider-specific metadata associated with this call.

invalid: Option<bool>

Set when lookup, JSON parsing, or schema validation still failed after the optional repair attempt.

error: Option<AiMuxError>

Typed failure associated with an invalid tool call.

Trait Implementations

impl Clone for ToolCall

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ToolCall

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ToolCall

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for ToolCall

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TS for ToolCall

type WithoutGenerics = ToolCall

If this type does not have generic parameters, then WithoutGenerics should just be Self. If the type does have generic parameters, then all generic parameters must be replaced with a dummy type, e.g ts_rs::Dummy or ().
The only requirement for these dummy types is that EXPORT_TO must be None.

type OptionInnerType = ToolCall

If the implementing type is std::option::Option<T>, then this associated type is set to T. All other implementations of TS should set this type to Self instead.

fn ident(cfg: &Config) -> String

Identifier of this type, excluding generic parameters.

fn docs() -> Option<String>

JSDoc comment to describe this type in TypeScript - when TS is derived, docs are automatically read from your doc comments or #[doc = ".."] attributes

fn name(cfg: &Config) -> String

Name of this type in TypeScript, including generic parameters

fn decl_concrete(cfg: &Config) -> String

Declaration of this type using the supplied generic arguments. The resulting TypeScript definition will not be generic. For that, see TS::decl(). If this type is not generic, then this function is equivalent to TS::decl().

fn decl(cfg: &Config) -> String

Declaration of this type, e.g. type User = { user_id: number, ... }. This function will panic if the type has no declaration.

fn inline(cfg: &Config) -> String

Formats this types definition in TypeScript, e.g { user_id: number }. This function will panic if the type cannot be inlined.

fn inline_flattened(cfg: &Config) -> String

Flatten a type declaration. This function will panic if the type cannot be flattened.

fn visit_generics(v: &mut impl TypeVisitor)

where Self: 'static,

Iterates over all type parameters of this type.

fn output_path() -> Option<PathBuf>

Returns the output path to where T should be exported, relative to the output directory. The returned path does not include any base directory.

fn visit_dependencies(v: &mut impl TypeVisitor)

where Self: 'static,

Iterates over all dependency of this type.

fn dependencies(cfg: &Config) -> Vec<Dependency>

where Self: 'static,

Resolves all dependencies of this type recursively.

fn export(cfg: &Config) -> Result<(), ExportError>

where Self: 'static,

Manually export this type to the filesystem. To export this type together with all of its dependencies, use TS::export_all.

fn export_all(cfg: &Config) -> Result<(), ExportError>

where Self: 'static,

Manually export this type to the filesystem, together with all of its dependencies. To export only this type, without its dependencies, use TS::export.

fn export_to_string(cfg: &Config) -> Result<String, ExportError>

where Self: 'static,

Manually generate bindings for this type, returning a String. This function does not format the output, even if the format feature is enabled.
