Struct ChatUsage 

pub struct ChatUsage {
    pub openai: Usage,
    pub extra: Map<String, Value>,
}

Chat Completions accounting with dialect-specific fields preserved for the response’s raw.

Fields

openai: Usage

The OpenAI-compatible accounting.

extra: Map<String, Value>

Fields this dialect adds.

Implementations

impl ChatUsage

pub fn to_normalized(&self) -> Usage

Normalize this accounting.

cached_input_tokens falls back to DeepSeek’s prompt_cache_hit_tokens, which reports cache activity outside prompt_tokens_details; reading only the OpenAI spelling would report no cache hit on a turn that was entirely served from cache. (Mistral’s num_cached_tokens is a typed field of Usage and handled by its own to_normalized.)

pub fn to_normalized_for(&self, quirks: &Quirks) -> Usage

Normalize this accounting for a dialect with quirks, as the chat wire does: Self::to_normalized, with the reasoning count left unreported where the dialect’s count cannot be trusted (Quirks::reliable_reasoning_count).
