Struct darling_core::ast::Fields

pub struct Fields<T> {
    pub style: Style,
    pub fields: Vec<T>,
}

Equivalent to syn::Fields, but replaces the AST element with a generic.

Fields

style: Style

fields: Vec<T>

Methods

impl<T> Fields<T>

pub fn empty_from(vd: &Fields) -> Self

pub fn split(self) -> (Style, Vec<T>)

Splits the Fields into its style and fields for further processing. Returns an empty Vec for Unit data.

pub fn is_newtype(&self) -> bool

Returns true if this variant's data makes it a newtype.

pub fn is_unit(&self) -> bool

pub fn is_tuple(&self) -> bool

pub fn is_struct(&self) -> bool

pub fn as_ref<'a>(&'a self) -> Fields<&'a T>

pub fn map<F, U>(self, map: F) -> Fields<U> where     F: FnMut(T) -> U,

pub fn iter(&self) -> Iter<T>

impl<F: FromField> Fields<F>

pub fn try_from(fields: &Fields) -> Result<Self>

Trait Implementations

impl<T: UsesLifetimes> UsesLifetimes for Fields<T>

fn uses_lifetimes<'a>(     &self,     options: &Options,     lifetimes: &'a LifetimeSet ) -> LifetimeRefSet<'a>

Returns the subset of the queried lifetimes that are used by the implementing syntax element.

fn uses_lifetimes_cloned(     &self,     options: &Options,     lifetimes: &LifetimeSet ) -> LifetimeSet

Find all used lifetimes, then clone them and return that set.

impl<T: UsesTypeParams> UsesTypeParams for Fields<T>

fn uses_type_params<'a>(     &self,     options: &Options,     type_set: &'a IdentSet ) -> IdentRefSet<'a>

Returns the subset of the queried type parameters that are used by the implementing syntax element.

fn uses_type_params_cloned(     &self,     options: &Options,     type_set: &IdentSet ) -> IdentSet

Find all type params using uses_type_params, then clone the found values and return the set.

impl<T: PartialEq> PartialEq<Fields<T>> for Fields<T>

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

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

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

This method tests for !=.

impl<T: Eq> Eq for Fields<T>

impl<T: Clone> Clone for Fields<T>

fn clone(&self) -> Fields<T>

impl<T> From<Style> for Fields<T>

fn from(style: Style) -> Self

Performs the conversion.

impl<T, U: Into<Vec<T>>> From<(Style, U)> for Fields<T>

fn from((style, fields): (Style, U)) -> Self

Performs the conversion.

impl<T> IntoIterator for Fields<T>

type Item = T

The type of the elements being iterated over.

type IntoIter = IntoIter<T>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<T: Debug> Debug for Fields<T>

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