Trait Implementations

impl Clone for FactDirection

fn clone(&self) -> FactDirection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for FactDirection

impl Debug for FactDirection

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

Formats the value using the given formatter.

impl Default for FactDirection

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FactDirection

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for FactDirection

impl Eq for FactDirection

impl FromStr for FactDirection

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<FactDirection, <Self as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for FactDirection

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 FactDirection

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

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for FactDirection

impl TryFrom<&str> for FactDirection

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<FactDirection, <Self as TryFrom<&str>>::Error>

Performs the conversion.
