Struct JsonLineEvent 

pub struct JsonLineEvent {
    pub event_type: String,
    pub extra: HashMap<String, Value>,
}

A single parsed JSONL event from --json output.

The event_type field corresponds to the "type" key in the JSON. All other fields are captured in extra.

Fields

event_type: String

extra: HashMap<String, Value>

Implementations

impl JsonLineEvent

pub fn session_id(&self) -> Option<&str>

Returns the session_id field, if present and a string.

pub fn thread_id(&self) -> Option<&str>

Returns the thread_id field, if present and a string.

pub fn is_turn_completed(&self) -> bool

Returns true when this is the terminal event of a successful turn.

pub fn is_turn_failed(&self) -> bool

Returns true when this is the terminal event of a failed turn.

pub fn usage(&self) -> Option<TokenUsage>

Token counts reported by a turn.completed event.

Returns None on any other event, or when no usage object is present. The CLI reports tokens, not money; see TokenUsage.

pub fn agent_message_text(&self) -> Option<String>

Assistant text carried by an item.completed agent-message item.

Returns None for any other event or item type.

Real output uses a type discriminator and a text field; see the schema block at the top of this module. An item_type discriminator and a content block array are also accepted, neither of them observed. Tolerating the unobserved shapes is deliberate: the previous parser committed to one exact layout and silently yielded empty results when it was wrong, which is the bug this replaces.

pub fn role(&self) -> Option<&str>

Returns the role field, if present and a string.

pub fn content_text(&self) -> Option<String>

Extracts concatenated text from a content blocks array.

Each block with "type": "text" contributes its "text" value. Returns None if there is no content array or no text blocks.

pub fn item_type(&self) -> Option<&str>

The item discriminator on an item.* event.

agent_message and command_execution are the observed values. This is the field to match on when narrowing an item event, and it is present on item.started as well as item.completed.

Accepts item_type as well as type for the same reason agent_message_text does.

pub fn command_execution(&self) -> Option<CommandExecution>

A shell command the model ran, from a command_execution item.

None for any other item. exit_code and status are only populated on item.completed; an item.started for the same command carries the command alone.

Trait Implementations

impl Clone for JsonLineEvent

fn clone(&self) -> JsonLineEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JsonLineEvent

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

impl<'de> Deserialize<'de> for JsonLineEvent

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for JsonLineEvent

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
