[−][src]Struct checkers::Machine

pub struct Machine { /* fields omitted */ }

Fake machine implementation to validate an allocation history.

Methods

impl Machine[src]

pub fn push(&mut self, event: Event) -> Result<(), Violation>[src]

Push an event into the machine.

Examples

Checks for a double-free:

use checkers::{Event, Machine};

let mut machine = Machine::default();

assert!(machine.push(Event::Allocation {
    ptr: 0.into(),
    size: 2,
    align: 1,
}).is_ok());

assert!(machine.push(Event::Deallocation {
    ptr: 0.into(),
    size: 2,
    align: 1,
}).is_ok());

assert!(machine.push(Event::Deallocation {
    ptr: 0.into(),
    size: 2,
    align: 1,
}).is_err());

Checks for a misaligned allocation:

use checkers::{Event, Machine};

let mut machine = Machine::default();

assert!(machine.push(Event::Allocation {
    ptr: 5.into(),
    size: 2,
    align: 4,
}).is_err());

Tries to deallocate part of other region:

use checkers::{Event, Machine};

let mut machine = Machine::default();

assert!(machine.push(Event::Allocation {
    ptr: 100.into(),
    size: 100,
    align: 1,
}).is_ok());

assert!(machine.push(Event::Deallocation {
    ptr: 150.into(),
    size: 50,
    align: 1,
}).is_err());

assert!(machine.push(Event::Deallocation {
    ptr: 100.into(),
    size: 50,
    align: 1,
}).is_err());

pub fn trailing_regions(&self) -> Vec<Region>[src]

Access all trailing regions (ones which have not been deallocated).
