Enum CacheType 

pub enum CacheType {
    Unsafe,
    Writeback,
}

Caching policy for the block device. Mirrors upstream verbatim.

Variants

Unsafe

Pass writes straight to the backing file (no host page cache).

Writeback

Buffer writes through the host page cache and flush on guest fsync.

Trait Implementations

impl Clone for CacheType

fn clone(&self) -> CacheType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CacheType

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

Formats the value using the given formatter.

impl Default for CacheType

fn default() -> CacheType

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CacheType

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CacheType

fn eq(&self, other: &CacheType) -> 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 CacheType

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
