Struct FaultConfig 

pub struct FaultConfig {
    pub open_rate: Option<f64>,
    pub read_rate: Option<f64>,
    pub write_rate: Option<f64>,
    pub partial_write_rate: Option<f64>,
    pub sync_rate: Option<f64>,
    pub resize_rate: Option<f64>,
    pub partial_resize_rate: Option<f64>,
    pub remove_rate: Option<f64>,
    pub scan_rate: Option<f64>,
}

Configuration for deterministic storage fault injection.

Each rate is a probability from 0.0 (never fail) to 1.0 (always fail).

Fields

open_rate: Option<f64>

Failure rate for open_versioned operations.

read_rate: Option<f64>

Failure rate for read_at operations.

write_rate: Option<f64>

Failure rate for write_at operations.

partial_write_rate: Option<f64>

Probability that a write failure is a partial write (some bytes written before failure) rather than a complete failure (no bytes written). Only applies when write_rate triggers a failure. Value from 0.0 (always complete failure) to 1.0 (always partial write).

sync_rate: Option<f64>

Failure rate for sync operations.

resize_rate: Option<f64>

Failure rate for resize operations.

partial_resize_rate: Option<f64>

Probability that a resize failure is partial (resized to an intermediate size before failure) rather than a complete failure (size unchanged). Only applies when resize_rate triggers a failure. Value from 0.0 (always complete failure) to 1.0 (always partial resize).

remove_rate: Option<f64>

Failure rate for remove operations.

scan_rate: Option<f64>

Failure rate for scan operations.

Implementations

impl Config

pub const fn open(self, rate: f64) -> Self

Set the open failure rate.

pub const fn read(self, rate: f64) -> Self

Set the read failure rate.

pub const fn write(self, rate: f64) -> Self

pub const fn remove(self, rate: f64) -> Self

Set the remove failure rate.

pub const fn scan(self, rate: f64) -> Self

Set the scan failure rate.

Trait Implementations

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Config

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Config

fn default() -> Config

Returns the “default value” for a type.
