Struct MessageDeltaUsage 

pub struct MessageDeltaUsage {
    pub cache_creation: Option<CacheCreation>,
    pub cache_creation_input_tokens: Option<i64>,
    pub cache_read_input_tokens: Option<i64>,
    pub input_tokens: Option<i64>,
    pub output_tokens: i64,
    pub server_tool_use: Option<ServerToolUsage>,
    pub service_tier: Option<MessageDeltaUsageServiceTier>,
}

message_delta.usage 累积值（注意：是累积，不是增量）。其它 字段（cache_*、server_tool_use 等）在收尾时也可能填充。

Trait Implementations

impl Clone for MessageDeltaUsage

fn clone(&self) -> MessageDeltaUsage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MessageDeltaUsage

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MessageDeltaUsage

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MessageDeltaUsage

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
