Fields

fs: FsFaultConfig

Filesystem fault rules.

clock: ClockFaultConfig

Clock fault configuration.

alloc: AllocFaultConfig

Memory allocator fault configuration.

process: ProcessFaultConfig

Subprocess fault rules.

network: NetworkFaultConfig

Network fault rules (for local loopback interception).

threading: ThreadSchedulingConfig

Thread scheduling configuration (Layer 2 ptrace only).

Implementations

impl FaultConfig

pub fn none() -> Self

Create an empty configuration (no faults injected).

pub fn merge(base: &FaultConfig, overlay: &FaultConfig) -> FaultConfig

Merge two configs: overlay values take precedence over base. Rules are concatenated (not replaced).

pub fn validate(&self) -> Vec<ConfigError>

Validate the configuration, returning a list of errors.

pub fn has_faults(&self) -> bool

Returns true if any fault injection is configured.

Trait Implementations

impl Clone for FaultConfig

fn clone(&self) -> FaultConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FaultConfig

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

Formats the value using the given formatter.

impl Default for FaultConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FaultConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FaultConfig

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for FaultConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
