Properties needed to generate code for a field in all the contexts where one may appear.

Fields

name_in_attr: String

The name presented to the user of the library. This will appear in error messages and will be looked when parsing names.

ident: &'a Ident

The name presented to the author of the library. This will appear in the setters or temporary variables which contain the values.

ty: &'a Type

The type of the field in the input.

default_expression: Option<DefaultExpression<'a>>

with_path: Path

map: Option<&'a Path>

skip: bool

multiple: bool

Methods

Trait Implementations

impl<'a> UsesTypeParams for Field<'a>

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

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<'a> PartialEq<Field<'a>> for Field<'a>

fn eq(&self, other: &Field<'a>) -> bool

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

fn ne(&self, other: &Field<'a>) -> bool

This method tests for !=.

impl<'a> Eq for Field<'a>

impl<'a> Clone for Field<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Field<'a>

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

Formats the value using the given formatter.
