Struct SessionUsage 

pub struct SessionUsage {
    pub input_tokens: u64,
    pub cached_input_tokens: Option<u64>,
    pub output_tokens: u64,
    pub total_cost: Decimal,
    pub tokens_unknown: bool,
    pub cost_unknown: bool,
}

Request totals for a session, independent of its current context window.

Fields

input_tokens: u64

Total input tokens, including cached input.

cached_input_tokens: Option<u64>

Cached input included in input_tokens. Older saves lack this breakdown.

output_tokens: u64

Total generated tokens across all requests.

total_cost: Decimal

Known request costs in USD, serialized without rounding.

tokens_unknown: bool

Historical token totals were not recorded for this session.

cost_unknown: bool

At least one request did not have pricing available.
