Enum FieldOrVariant

pub enum FieldOrVariant<'a> {
    Field(&'a Field),
    Variant(&'a Variant),
}

Enum to encapsulate either a field from a struct or a variant from an enum.

Variants

Field(&'a Field)

Represents a field within a struct or union.

Variant(&'a Variant)

Represents a variant within an enum.

Implementations

impl FieldOrVariant<'_>

pub fn attrs(&self) -> &Vec<Attribute>

Returns a reference to the attributes of the item.

pub fn vis(&self) -> Option<&Visibility>

Returns a reference to the visibility of the item.

pub fn mutability(&self) -> Option<&FieldMutability>

Returns a reference to the mutability of the item.

pub fn ident(&self) -> Option<&Ident>

Returns a reference to the identifier of the item.

pub fn typ(&self) -> Option<&Type>

Returns an iterator over elements of the item.

pub fn fields(&self) -> Option<&Fields>

Returns a reference to the fields of the item.

pub fn discriminant(&self) -> Option<&(Eq, Expr)>

Returns a reference to the discriminant of the item.

Trait Implementations

impl<'a> Clone for FieldOrVariant<'a>

fn clone(&self) -> FieldOrVariant<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for FieldOrVariant<'a>

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

Formats the value using the given formatter.

impl<'a> From<&'a Field> for FieldOrVariant<'a>

fn from(field: &'a Field) -> Self

Converts to this type from the input type.

impl<'a> From<&'a Variant> for FieldOrVariant<'a>

fn from(variant: &'a Variant) -> Self

Converts to this type from the input type.

impl<'a> PartialEq for FieldOrVariant<'a>

fn eq(&self, other: &FieldOrVariant<'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 ToTokens for FieldOrVariant<'_>

fn to_tokens(&self, tokens: &mut TokenStream)

Write self to the given TokenStream.

fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

fn into_token_stream(self) -> TokenStream

where Self: Sized,

Convert self directly into a TokenStream object.
