Struct FullCallGraph 

pub struct FullCallGraph { /* private fields */ }

Full call graph including execution time and number of calls between functions/spans.

This graph is a directed graph linking different SpanTiming by the number of time a given span was the child of another one.

Examples

Code that looks like this

#[time_graph::instrument]
fn start() {
    inside();
    inside();
    inner();
}

#[time_graph::instrument]
fn inside() {
   inner();
}

#[time_graph::instrument]
fn inner() {
    // do stuff
}

Will result in a graph like this, where the number near the edge correspond to the number of time a given span called another one.

            | start, called 1 |
               /           |
             /  2          |
           /               |  1
  | inside, called 2 |     |
                \          |
                2 \        |
                    \      |
                 | inner, called 3 |

Implementations

impl FullCallGraph

pub fn spans(&self) -> impl Iterator<Item = &TimedSpan>

Get the full list of spans/functions known by this graph

pub fn calls(&self) -> impl Iterator<Item = Calls> + '_

Get the list of calls between spans in this graph

pub fn as_dot(&self) -> String

Get the full graph in graphviz dot format.

The exact output is unstable and should not be relied on.
