Trait Implementations

impl<T> FromGenerics for WithOriginal<T, Generics> where
    T: FromGenerics, 

fn from_generics(value: &Generics) -> Result<WithOriginal<T, Generics>, Error>

impl<T> FromDeriveInput for WithOriginal<T, DeriveInput> where
    T: FromDeriveInput, 

fn from_derive_input(
    value: &DeriveInput
) -> Result<WithOriginal<T, DeriveInput>, Error>

Create an instance from syn::DeriveInput, or return an error.

impl<T> FromGenericParam for WithOriginal<T, GenericParam> where
    T: FromGenericParam, 

fn from_generic_param(
    value: &GenericParam
) -> Result<WithOriginal<T, GenericParam>, Error>

impl<T> FromField for WithOriginal<T, Field> where
    T: FromField, 

fn from_field(value: &Field) -> Result<WithOriginal<T, Field>, Error>

impl<T, O> PartialEq<WithOriginal<T, O>> for WithOriginal<T, O> where
    O: PartialEq<O>,
    T: PartialEq<T>, 

fn eq(&self, __arg_0: &WithOriginal<T, O>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &WithOriginal<T, O>) -> bool

This method tests for !=.

impl<T, O> Clone for WithOriginal<T, O> where
    O: Clone,
    T: Clone, 

fn clone(&self) -> WithOriginal<T, O>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> FromMeta for WithOriginal<T, Meta> where
    T: FromMeta, 

fn from_meta(value: &Meta) -> Result<WithOriginal<T, Meta>, Error>

Create an instance from a syn::Meta by dispatching to the format-appropriate trait function. This generally should not be overridden by implementers.

fn from_nested_meta(item: &NestedMeta) -> Result<Self, Error>

fn from_word() -> Result<Self, Error>

Create an instance from the presence of the word in the attribute with no additional options specified.

fn from_list(items: &[NestedMeta]) -> Result<Self, Error>

Create an instance from a list of nested meta items.

fn from_value(value: &Lit) -> Result<Self, Error>

Create an instance from a literal value of either foo = "bar" or foo("bar"). This dispatches to the appropriate method based on the type of literal encountered, and generally should not be overridden by implementers.

fn from_char(value: char) -> Result<Self, Error>

Create an instance from a char literal in a value position.

fn from_string(value: &str) -> Result<Self, Error>

Create an instance from a string literal in a value position.

fn from_bool(value: bool) -> Result<Self, Error>

Create an instance from a bool literal in a value position.

impl<T> FromVariant for WithOriginal<T, Variant> where
    T: FromVariant, 

fn from_variant(value: &Variant) -> Result<WithOriginal<T, Variant>, Error>

Create an instance from syn::Variant, or return an error.

impl<T> FromTypeParam for WithOriginal<T, TypeParam> where
    T: FromTypeParam, 

fn from_type_param(
    value: &TypeParam
) -> Result<WithOriginal<T, TypeParam>, Error>

impl<T, O> Eq for WithOriginal<T, O> where
    O: Eq,
    T: Eq, 

impl<T, O> Debug for WithOriginal<T, O> where
    O: Debug,
    T: Debug, 

fn fmt(&self, __arg_0: &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.
