Struct SessionUsage 

#[non_exhaustive]
pub struct SessionUsage {
    pub input_tokens: u64,
    pub output_tokens: u64,
    pub cache_creation: Option<CacheCreationUsage>,
    pub cache_read_input_tokens: u64,
}

Available on crate feature managed-agents-preview only.

Cumulative token usage on a session.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

input_tokens: u64

Uncached input tokens billed across all model calls.

output_tokens: u64

Total output tokens across all model calls.

cache_creation: Option<CacheCreationUsage>

Tokens written to the prompt cache, broken down by cache TTL.

cache_read_input_tokens: u64

Tokens served from the prompt cache (cheaper read path).

Trait Implementations

impl Clone for SessionUsage

fn clone(&self) -> SessionUsage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SessionUsage

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

Formats the value using the given formatter.

impl Default for SessionUsage

fn default() -> SessionUsage

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SessionUsage

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SessionUsage

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for SessionUsage

impl StructuralPartialEq for SessionUsage
