Struct Field 

#[non_exhaustive]
pub struct Field {
    pub attributes: Vec<Attribute>,
    pub visibility: Visibility,
    pub name: Ident,
    pub ty: Option<(Colon, Type)>,
}

A field as part of a struct or a tuple body.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

attributes: Vec<Attribute>

Attributes associated with field.

visibility: Visibility

The visibility of the field

name: Ident

Name of the field.

ty: Option<(Colon, Type)>

The type.

Trait Implementations

impl Debug for Field

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

Formats the value using the given formatter.

impl OptionSpanned for Field

fn option_span(&self) -> Option<Span>

Get the optional span of the type.

impl Parse for Field

fn parse(parser: &mut Parser<'_>) -> Result<Self, Error>

Parse the current item from the parser.

impl PartialEq for Field

fn eq(&self, other: &Field) -> 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 Spanned for Field

fn span(&self) -> Span

Get the span of the type.

impl ToTokens for Field

fn to_tokens( &self, context: &mut MacroContext<'_, '_, '_>, stream: &mut TokenStream, ) -> Result<()>

Turn the current item into tokens.

impl TryClone for Field

fn try_clone(&self) -> Result<Self>

Try to clone the current value, raising an allocation error if it’s unsuccessful.

fn try_clone_from(&mut self, source: &Self) -> Result<(), Error>

Performs copy-assignment from source.

impl Eq for Field

impl StructuralPartialEq for Field
