Disk

Disk-backed retained feed tail.

Implementations

impl DerivedStateReplayBackend

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

Returns the stable env/config representation for the backend.

pub const fn from_config_value(value: &str) -> Option<Self>

Parses one env/config value into a backend.

Trait Implementations

impl Clone for DerivedStateReplayBackend

fn clone(&self) -> DerivedStateReplayBackend

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DerivedStateReplayBackend

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

Formats the value using the given formatter.

impl Default for DerivedStateReplayBackend

fn default() -> DerivedStateReplayBackend

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DerivedStateReplayBackend

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for DerivedStateReplayBackend

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

Formats the value using the given formatter.

impl PartialEq for DerivedStateReplayBackend

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
