Enum syn_helpers::Fields

pub enum Fields {
    Named(Vec<NamedField>, Vec<Attribute>),
    Unnamed(Vec<UnnamedField>, Vec<Attribute>),
    Unit(Vec<Attribute>),
}

Represents the fields in a structure. This could be the fields on a struct or the fields in the variant of a enum

Variants

Named(Vec<NamedField>, Vec<Attribute>)

*name* { X: String }

Unnamed(Vec<UnnamedField>, Vec<Attribute>)

*name*(String)

Unit(Vec<Attribute>)

No fields *name*

Implementations

impl Fields

pub fn get_field_attributes(&self) -> &[Attribute]

pub fn fields_iterator( &self ) -> impl ExactSizeIterator<Item = NamedOrUnnamedField<'_>>

pub fn fields_iterator_mut( &mut self ) -> impl ExactSizeIterator<Item = NamedOrUnnamedFieldMut<'_>>

pub fn to_pattern(&self, path: Path, type_of_self: TypeOfSelf) -> TokenStream

pub fn to_pattern_with_config( &self, path: Path, type_of_self: TypeOfSelf, name_postfix: &'static str ) -> TokenStream

pub fn to_constructor<'b>( &'b self, generator: impl Fn(NamedOrUnnamedField<'b>) -> Result<Expr, Box<dyn Error>>, constructor: Path ) -> Result<Expr, Box<dyn Error>>

pub fn get_field_by_member( &self, member: Member ) -> Option<NamedOrUnnamedField<'_>>

Will just return None if member is not of matching form. Also will return None if cannot find the field

pub fn get_field_by_member_mut( &mut self, member: Member ) -> Option<NamedOrUnnamedFieldMut<'_>>

Will just return None if member is not of matching form. Also will return None if cannot find the field
