Expand description
A procedural macro attribute for instrumenting functions with
time-graph
.
time-graph
provides always-on profiling for your code, allowing to
record the execution time of functions, spans inside these functions and the
actual call graph at run-time. This crate provides the
#[instrument]
procedural macro attribute.
Note that this macro is also re-exported by the main time-graph
crate.
§Usage
First, add this to your Cargo.toml
:
[dependencies]
time-graph-macros = "0.1.0"
The #[instrument]
attribute can now be added to a function
to automatically create a time-graph
callsite, and enter the
corresponding span when that function is called. For example:
use time_graph_macros::instrument;
#[instrument]
pub fn my_function(my_arg: usize) {
// ...
}
Attribute Macros§
- instrument
- Instruments a function to create and enter a
time-graph
span every time the function is called.
