ProfileData

Struct ProfileData 

Source
pub struct ProfileData {
    pub call_counts: HashMap<String, u64>,
    pub hot_functions: Vec<String>,
    pub edge_counts: HashMap<(String, String), u64>,
}
Expand description

Collected profiling data: call frequencies and call-graph edge weights.

Fields§

§call_counts: HashMap<String, u64>

How many times each function was called.

§hot_functions: Vec<String>

Functions whose call count exceeds the hot threshold.

§edge_counts: HashMap<(String, String), u64>

Edge weights in the dynamic call graph: (caller, callee) -> count.

Implementations§

Source§

impl ProfileData

Source

pub fn new() -> Self

Create an empty ProfileData.

Source

pub fn record_call(&mut self, func: &str)

Record one call to func.

Source

pub fn record_edge(&mut self, caller: &str, callee: &str)

Record one traversal of the call-graph edge caller → callee.

Source

pub fn mark_hot(&mut self, threshold: u64)

Populate hot_functions with every function whose call count exceeds threshold. The list is sorted descending by call count for deterministic output.

Source

pub fn is_hot(&self, func: &str) -> bool

Return true if func is in the hot-functions list.

Source

pub fn top_k_functions(&self, k: usize) -> Vec<(String, u64)>

Return the top-k functions sorted descending by call count. If k exceeds the number of recorded functions the full list is returned.
