Metadata about a cached function

Fields

compiled_at: SystemTime

When the function was compiled

execution_count: u64

How many times this function has been executed

total_execution_time_ns: u64

Total execution time in nanoseconds

avg_execution_time_ns: f64

Average execution time in nanoseconds

function_size_bytes: usize

Size of the compiled function in bytes

compilation_time_ns: u64

Compilation time in nanoseconds

is_hot: bool

Whether this function is performance-critical (frequently used)

last_accessed: Instant

Last access time

effectiveness_score: f64

Function effectiveness score (performance improvement over naive implementation)
