Struct TurnUsage 

pub struct TurnUsage {
    pub input_tokens: u64,
    pub output_tokens: u64,
    pub cache_read_input_tokens: u64,
    pub cache_creation_input_tokens: u64,
    pub cache_creation_5m: Option<u64>,
    pub cache_creation_1h: Option<u64>,
    pub model: Option<String>,
}

Token-usage summary for a completed agent turn.

Mirrors the shape of runtime::types::SessionEvent::Usage so that consumers of the RPC protocol have identical fields without depending on the internal runtime type.

Fields

input_tokens: u64

Prompt tokens sent to the model.

output_tokens: u64

Completion tokens returned by the model.

cache_read_input_tokens: u64

Tokens served from the prompt cache (not billed at full rate).

cache_creation_input_tokens: u64

Tokens written into the prompt cache during this turn.

cache_creation_5m: Option<u64>

5-minute-TTL share of cache writes. Optional, omitted when unknown.

cache_creation_1h: Option<u64>

1-hour-TTL share of cache writes. Optional, omitted when unknown.

model: Option<String>

The model identifier used for this turn, if known.

Trait Implementations

impl Clone for TurnUsage

fn clone(&self) -> TurnUsage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TurnUsage

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TurnUsage

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for TurnUsage

impl PartialEq for TurnUsage

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

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.
