original: O

Implementations

impl<T, O> WithOriginal<T, O>

pub fn new(parsed: T, original: O) -> WithOriginal<T, O>

Trait Implementations

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

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

where T: Debug, O: Debug,

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

Formats the value using the given formatter.

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> FromField for WithOriginal<T, Field>

where T: FromField,

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

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

where T: FromGenericParam,

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

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

where T: FromGenerics,

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

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_none() -> Option<Self>

When a field is omitted from a parent meta-item, from_none is used to attempt recovery before a missing field error is generated.

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_expr(expr: &Expr) -> Result<Self, Error>

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> FromTypeParam for WithOriginal<T, TypeParam>

where T: FromTypeParam,

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

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, O> PartialEq for WithOriginal<T, O>

where T: PartialEq, O: PartialEq,

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

where T: Eq, O: Eq,
