Struct SessionCost 

pub struct SessionCost {
    pub total_input_tokens: u64,
    pub total_output_tokens: u64,
    pub total_cache_creation_tokens: u64,
    pub total_cache_read_tokens: u64,
    pub total_reasoning_tokens: u64,
}

Cumulative token cost for a session, stored in .meta.json.

Fields

total_input_tokens: u64

total_output_tokens: u64

total_cache_creation_tokens: u64

total_cache_read_tokens: u64

total_reasoning_tokens: u64

Goal 273: reasoning / thinking tokens summed across the session. Priced at the model’s output rate (see ModelPricing::cost_usd).
