Enum FlakeyFeatureArg 

pub enum FlakeyFeatureArg {
    DropWrites,
    ErrorWrites,
    CorruptBioByte(u64, Direction, u8, u64),
}

Flakey target optional feature parameters: If no feature parameters are present, during the periods of unreliability, all I/O returns errors.

Variants

DropWrites

drop_writes:

All write I/O is silently ignored. Read I/O is handled correctly.

ErrorWrites

error_writes:

All write I/O is failed with an error signalled. Read I/O is handled correctly.

CorruptBioByte(u64, Direction, u8, u64)

corrupt_bio_byte <Nth_byte> <direction> <value> <flags>:

During <down interval>, replace <Nth_byte> of the data of each matching bio with <value>.

• <Nth_byte>: The offset of the byte to replace. Counting starts at 1, to replace the first byte.
• <direction>: Either ‘r’ to corrupt reads or ‘w’ to corrupt writes. ‘w’ is incompatible with drop_writes.
• <value>: The value (from 0-255) to write.
• <flags>: Perform the replacement only if bio->bi_opf has all the selected flags set.

Trait Implementations

impl Clone for FlakeyFeatureArg

fn clone(&self) -> FlakeyFeatureArg

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FlakeyFeatureArg

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

Formats the value using the given formatter.

impl Display for FlakeyFeatureArg

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

Formats the value using the given formatter.

impl Hash for FlakeyFeatureArg

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FlakeyFeatureArg

fn eq(&self, other: &FlakeyFeatureArg) -> 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.
