Trait Implementations

impl<A> Clone for DerivError<A>

where A: Hash + PartialEq + Eq + Display + Clone,

fn clone(&self) -> DerivError<A>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<A> Debug for DerivError<A>

where A: Hash + PartialEq + Eq + Display + Debug,

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

Formats the value using the given formatter.

impl<'de, A> Deserialize<'de> for DerivError<A>

where A: Hash + PartialEq + Eq + Display + Deserialize<'de>,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<A> Display for DerivError<A>

where A: Hash + PartialEq + Eq + Display + Display, Box<Rbe<A>>: Display, Bag<A>: Display, Failures<A>: Display, Box<Bag<A>>: Display,

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

Formats the value using the given formatter.

impl<A> Error for DerivError<A>

where A: Hash + PartialEq + Eq + Display, Self: Debug + Display,

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl<A> Hash for DerivError<A>

where A: Hash + PartialEq + Eq + Display + Hash,

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<A> PartialEq for DerivError<A>

where A: Hash + PartialEq + Eq + Display + PartialEq,

fn eq(&self, other: &DerivError<A>) -> 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<A> Serialize for DerivError<A>

where A: Hash + PartialEq + Eq + Display + Serialize,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<A> Eq for DerivError<A>

where A: Hash + PartialEq + Eq + Display + Eq,

impl<A> StructuralPartialEq for DerivError<A>

where A: Hash + PartialEq + Eq + Display,
