Trait Implementations

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

fn from_derive_input(value: &DeriveInput) -> Result<Self>

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

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

fn from_field(value: &Field) -> Result<Self>

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

fn from_generic_param(value: &GenericParam) -> Result<Self>

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

fn from_generics(value: &Generics) -> Result<Self>

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

fn from_meta(value: &Meta) -> Result<Self>

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>

fn from_word() -> Result<Self>

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

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

Create an instance from a list of nested meta items.

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

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>

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

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

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

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

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

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

fn from_type_param(value: &TypeParam) -> Result<Self>

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

fn from_variant(value: &Variant) -> Result<Self>

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

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

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

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

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

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

This method tests for !=.

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

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

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

Formats the value using the given formatter.
