Struct MessageUsage 

pub struct MessageUsage {
    pub model: String,
    pub prompt_tokens: usize,
    pub completion_tokens: usize,
    pub duration_ms: u64,
}

Token usage attributed to a single chat message.

Populated from crate::session::SessionEvent::UsageReport after a provider completion returns. Attached to the most recent assistant / tool-call message produced by that completion.

Examples

use codetether_agent::tui::chat::message::MessageUsage;

let usage = MessageUsage {
    model: "anthropic/claude-opus-4".into(),
    prompt_tokens: 1523,
    completion_tokens: 284,
    duration_ms: 4210,
};
assert_eq!(usage.prompt_tokens, 1523);

Fields

model: String

Model that produced this completion.

prompt_tokens: usize

Input / prompt tokens charged for this completion.

completion_tokens: usize

Output / completion tokens produced by this completion.

duration_ms: u64

Wall-clock latency of the provider request in milliseconds.

Trait Implementations

impl Clone for MessageUsage

fn clone(&self) -> MessageUsage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MessageUsage

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MessageUsage

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MessageUsage

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
