Struct TimelineQuery

Source

pub struct TimelineQuery { /* private fields */ }

Expand description

Timeline query engine

Provides functionality to query events based on time ranges and other temporal criteria.

Implementations§

Source §

impl TimelineQuery

Source

pub fn new(event_store: Arc<EventStore>) -> Self

Create a new timeline query

Source

pub fn get_events_in_range(&self, start: u64, end: u64) -> Vec<MemoryEvent>

Get events in a time range

§Arguments

start - Start timestamp (inclusive)
end - End timestamp (exclusive)

Source

pub fn get_allocations_in_range(&self, start: u64, end: u64) -> Vec<MemoryEvent>

Get allocation events in a time range

§Arguments

start - Start timestamp (inclusive)
end - End timestamp (exclusive)

Source

pub fn get_deallocations_in_range( &self, start: u64, end: u64, ) -> Vec<MemoryEvent>

Get deallocation events in a time range

§Arguments

start - Start timestamp (inclusive)
end - End timestamp (exclusive)

Source

pub fn get_thread_events_in_range( &self, thread_id: u64, start: u64, end: u64, ) -> Vec<MemoryEvent>

Get events for a specific thread in a time range

§Arguments

thread_id - The thread ID to filter by
start - Start timestamp (inclusive)
end - End timestamp (exclusive)

Source

pub fn get_memory_usage_over_time( &self, start: u64, end: u64, interval_ms: u64, ) -> Vec<(u64, usize)>

Get memory usage over time with cumulative tracking.

§Arguments

start - Start timestamp (inclusive)
end - End timestamp (exclusive)
interval_ms - Interval between snapshots in milliseconds

§Returns

Vector of (timestamp, cumulative_memory_bytes) tuples showing the actual memory usage at each point in time.

Source

pub fn get_peak_memory_in_range(&self, start: u64, end: u64) -> usize

Get peak memory usage in a time range

§Arguments

start - Start timestamp (inclusive)
end - End timestamp (exclusive)

§Note

This function processes all events in chronological order to find the true peak memory usage, not just the maximum interval delta.

Source

pub fn get_event_rate(&self, start: u64, end: u64) -> f64

Get event rate (events per second) in a time range

§Arguments

start - Start timestamp (inclusive)
end - End timestamp (exclusive)
