Struct Faults 

pub struct Faults { /* private fields */ }

The armed set plus the run’s generator.

Implementations

impl Faults

pub fn none() -> Faults

Nothing armed but the weather that is always true: Fault::StaleVncPort is the provider’s normal behaviour, not an exception, and a mock that hid it by default would leave the toggle cure untested.

pub fn quiet() -> Faults

Nothing at all, not even the provider’s normal. For the one test that asserts the mock can be quiet.

pub fn seeded(seed: u64) -> Faults

Weather derived from one number. Every fault whose Fault::seeded_rate_per_mille is non-zero is armed, and fires at that rate off a stream derived from the seed and the fault’s own name — so adding a tenth fault does not renumber the other nine’s decisions, and a seed printed today still replays tomorrow.

pub fn seed(&self) -> u64

pub fn arm(&self, f: Fault)

pub fn disarm(&self, f: Fault)

pub fn is_armed(&self, f: Fault) -> bool

pub fn fires(&self, f: Fault) -> bool

Ask whether f fires NOW. Deterministic when armed by name; seeded when the run has weather; sticky faults answer true forever once they have answered it once.

pub fn fired(&self) -> Vec<Fault>

Everything that has fired at least once, for a run’s report line.

Trait Implementations

impl Default for Faults

fn default() -> Self

Returns the “default value” for a type.
