Implementations

impl<'a, T> MaybeBorrowed<'a, T>

Check if Self contains a owned type. Inverse of MaybeBorrowed::is_borrowed.

Trait Implementations

impl<'a, Gen> AttachGenerics<'a> for MaybeBorrowed<'a, Gen>where Gen: Generatable<'a>,

type Output = MaybeBorrowed<'a, Gen>

An optional type wrapper around the type the generics will be attached to Used by this crate to wrap types with MaybeBorrowed to allow both references and owned types to be represented by the same type.

fn with_optional_generics<G>( self, generics: Option<G> ) -> WithGenerics<'a, Self::Output>where G: Into<MaybeBorrowed<'a, Generics>>,

fn with_generics<G>(self, generics: G) -> WithGenerics<'a, Self::Output>where G: Into<MaybeBorrowed<'a, Generics>>, Self: Sized,

Attach some generics G to Self. This allows for the generics to to not exactly be syn::Generics but any type that can be turned into MaybeBorrowed<syn::Generics>. This allows for both &syn::Generics and syn::Generics to be attached using the same trait.

impl<'a, T: Debug> Debug for MaybeBorrowed<'a, T>

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

Formats the value using the given formatter.

impl<'a, T> Ord for MaybeBorrowed<'a, T>where T: Ord,

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,
