Enum ActivityEventKind 

pub enum ActivityEventKind {
    Message {
        role: MessageRole,
        text: String,
    },
    ToolCall {
        tool: String,
        call_id: String,
        input: Value,
    },
    ToolResult {
        call_id: String,
        output: Value,

    },
    Progress {
        detail: ProgressDetail,
    },
    Stop {
        reason: StopKind,
    },
    Raw {
        source: String,

    Delta {
        message_id: String,
        text_fragment: String,
    },
}

The payload of an ActivityEvent — the classified kind of transcript signal.

Kinds are LOCKED: Message, ToolCall, ToolResult, Progress, Stop, Raw, plus Delta carried on the same channel but flagged ephemeral (forwarded to the WS, never persisted). Self::Raw is the passthrough fallback — critical for the harness-agnostic path and for forward-compat when a harness adds an event shape the adapter does not yet map.

Variants

Message

A complete conversational message (assistant text/thinking, an operator turn, etc.).

Fields

role: MessageRole

Who the message is attributed to.

text: String

The message text.

ToolCall

The agent invoked a tool/function with structured input.

Fields

tool: String

The tool/function name.

call_id: String

Correlation id linking this call to its eventual Self::ToolResult.

input: Value

The structured tool input.

ToolResult

A tool/function returned a result for a prior Self::ToolCall.

Fields

call_id: String

Correlation id matching the originating Self::ToolCall.

output: Value

The structured tool output.

is_error: bool

Whether the tool reported an error result.

Progress

A fine-grained, non-terminal progress signal.

Fields

detail: ProgressDetail

The progress detail.

Stop

The agent run reached a terminal boundary.

Fields

reason: StopKind

Why the run stopped.

Raw

Passthrough fallback for an unmapped or other-harness line.

Carries the source label the adapter observed and the raw value verbatim, so nothing is ever silently dropped and the harness-agnostic path stays lossless.

Fields

source: String

A label identifying where the raw value came from (adapter-defined).

value: Value

The raw value, passed through verbatim.

Delta

An ephemeral token delta — forwarded to the WS only, never persisted.

Always carried with ActivityEvent::ephemeral set to true.

Fields

message_id: String

The id of the message this fragment belongs to.

text_fragment: String

The incremental text fragment.

Trait Implementations

impl Clone for ActivityEventKind

fn clone(&self) -> ActivityEventKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ActivityEventKind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ActivityEventKind

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ActivityEventKind

fn eq(&self, other: &ActivityEventKind) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for ActivityEventKind

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.

impl StructuralPartialEq for ActivityEventKind

impl TS for ActivityEventKind

type WithoutGenerics = ActivityEventKind

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 = ActivityEventKind

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 ActivityEventKind: '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 ActivityEventKind: '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.
