cpm-rs
Single crate for Critical Path Method calculation.
Functionality
- File parser for predefined tasks. (May be removed later.)
- Critical path calculation.
- Calculation of number of maximum parallel tasks at a time.
- Indexed integer or floating point time units.
Future functionality
- Dependency circle check.
- Shiftable tasks.
- Graph visualization.
- Crate features.
Limitations
- Does not check circles in task dependencies.
- Does not utilize multiple utilize multiple threads for path calculations.
- Does not have a depth / performance limit on recursive path calculations.
Usage
Example 1: read tasks from file
```rust
fn main() {
let mut scheduler = scheduler::Scheduler::new();
let args: Vec = env::args().collect();
if args.len() < 2 {
eprintln!("Please provide an input file path!");
exit(1);
}
match inputparser::parseinputfile(&args[1]) {
Ok(tasklist) => { scheduler.schedule(task_list); },
Err(e) => {eprintln!("Error: {}", e); exit(1);},
}
}
```
Example 2: add tasks from code
```rust
fn main() {
let mut scheduler = Scheduler::new();
scheduler.addtask(CustomTask::new(
"TaskA".tostring()
, 1
, vec!{}
));
scheduler.addtask(CustomTask::new(
"SidetaskB".tostring()
, 3
, vec!{"TaskA".tostring()}
));
scheduler.addtask(CustomTask::new(
"SidetaskC".tostring()
, 2
, vec!{"TaskB".tostring()}
));
scheduler.addtask(CustomTask::new(
"Finish".tostring()
, 1
, vec!{"SidetaskB".tostring(), "SidetaskC".to_string()}
));
match scheduler.schedule() {
Ok(()) => {},
Err(e) => {eprintln!("Error: {}", e); exit(1);},
}
}
```
