Enum FaultClass 

pub enum FaultClass {
    TornWrite,
    MisdirectedWrite,
    BitRot,
    LostWrite,
}

The four modeled storage fault classes (ADR 0074 §1). Crash-at-any-point is modeled separately by the existing buggify! crash boundaries.

Variants

TornWrite

A write persists only a prefix of its buffer, cut at a sector boundary.

MisdirectedWrite

A write persists the correct bytes at a wrong offset, reporting success.

BitRot

Stored bytes acquire a flipped bit between the write and a later read.

LostWrite

The write (or its fsync effect) is dropped entirely; success is reported.

Implementations

impl FaultClass

pub const ALL: [Self; 4]

Every class, in a stable order (the order knobs are rolled in).

pub const fn name(self) -> &'static str

The stable, machine-readable name a campaign selects the knob by.

pub fn from_name(name: &str) -> Option<Self>

Parse a class from its name.

Trait Implementations

impl Ord for FaultClass

fn cmp(&self, other: &FaultClass) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

impl PartialEq for FaultClass

fn eq(&self, other: &FaultClass) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for FaultClass

fn partial_cmp(&self, other: &FaultClass) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool
