Expand description
A builder for implementing a trait for enums.
Implementations
sourceimpl<'a> EnumImpl<'a>
impl<'a> EnumImpl<'a>
sourcepub fn from_trait<I>(
data: &'a EnumData,
trait_path: Path,
supertraits_types: I,
trait_def: ItemTrait
) -> Self where
I: IntoIterator<Item = Ident>,
I::IntoIter: ExactSizeIterator,
pub fn from_trait<I>(
data: &'a EnumData,
trait_path: Path,
supertraits_types: I,
trait_def: ItemTrait
) -> Self where
I: IntoIterator<Item = Ident>,
I::IntoIter: ExactSizeIterator,
Creates a new EnumImpl
from a trait definition.
The following items are ignored:
- Generic associated types (GAT) (
TraitItem::Method
that has generics) TraitItem::Const
TraitItem::Macro
TraitItem::Verbatim
Panics
Panics if a trait method has a body, no receiver, or a receiver other than the following:
&self
&mut self
self
self: Pin<&Self>
self: Pin<&mut Self>
pub fn set_trait(&mut self, path: Path)
sourcepub fn push_generic_param(&mut self, param: GenericParam)
pub fn push_generic_param(&mut self, param: GenericParam)
Appends a generic type parameter to the back of generics.
sourcepub fn push_where_predicate(&mut self, predicate: WherePredicate)
pub fn push_where_predicate(&mut self, predicate: WherePredicate)
Appends a predicate to the back of where
-clause.
sourcepub fn push_method(&mut self, item: TraitItemMethod)
pub fn push_method(&mut self, item: TraitItemMethod)
Appends a method to impl items.
Panics
Panics if a trait method has a body, no receiver, or a receiver other than the following:

self
self: Pin<&Self>
self: Pin<&mut Self>
sourcepub fn append_items_from_trait(&mut self, trait_def: ItemTrait)
pub fn append_items_from_trait(&mut self, trait_def: ItemTrait)
Appends items from a trait definition to impl items.
