Trait for output formatters

This trait defines the interface for formatting various types of usage data. Implementations can provide different output formats (table, JSON, CSV, etc.).

§Example Implementation

use ccstat_terminal::output::OutputFormatter;
use ccstat_core::aggregation_types::{DailyUsage, DailyInstanceUsage, SessionUsage, MonthlyUsage, WeeklyUsage, SessionBlock, Totals};

struct CustomFormatter;

impl OutputFormatter for CustomFormatter {
    fn format_daily(&self, data: &[DailyUsage], totals: &Totals) -> String {
        format!("Total days: {}, Total cost: ${:.2}", data.len(), totals.total_cost)
    }

    fn format_daily_by_instance(&self, data: &[DailyInstanceUsage], totals: &Totals) -> String {
        format!("Total instances: {}", data.len())
    }

    fn format_sessions(&self, data: &[SessionUsage], totals: &Totals, _tz: &chrono_tz::Tz) -> String {
        format!("Total sessions: {}", data.len())
    }

    fn format_monthly(&self, data: &[MonthlyUsage], totals: &Totals) -> String {
        format!("Total months: {}", data.len())
    }

    fn format_weekly(&self, data: &[WeeklyUsage], totals: &Totals) -> String {
        format!("Total weeks: {}", data.len())
    }

    fn format_blocks(&self, data: &[SessionBlock], _tz: &chrono_tz::Tz) -> String {
        format!("Total blocks: {}", data.len())
    }
}
