Struct Telety

pub struct Telety<'item> { /* private fields */ }

Wraps an Item which has the #[telety] attribute to provide additional information allowing it to be reflected outside its original context.

Implementations

impl<'item> Telety<'item>

pub fn new(item: &'item Item) -> Result<Self>

Generate telety information for the Item.
The item must have a proper #[telety(...)] attribute.
Usually this item will come from the telety-generated macro with the same name as the item.

pub fn options(&self) -> &Options

pub fn alias_map(&self) -> &Map<'_>

Provides the alias::Map for this item, which describes the mapping of types appearing in the item to the aliases created for them.

pub fn generics_visitor<'a>( &self, generic_arguments: impl IntoIterator<Item = &'a GenericArgument>, ) -> Result<ApplyGenericArguments<'_>>

Create a visitor which substitutes generic parameters as if this type were monomorphized with the provided generic arguments.
For example, if we have a type:

#[telety(crate)]
struct S<T, U, V = T>(T, U, V);

and provided the arguments [i32, u64], the visitor would replace types T with i32, U with u64, and V with i32.
See syn::visit_mut.

pub fn item(&self) -> &Item

The Item this describes

pub fn path(&self) -> Path

The Path to the item, using the crate name, not the crate:: qualifier, and no arguments on the item.

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

The Attributes on the Item

pub fn containing_mod_path(&self) -> Path

The Path of the module containing this Item. Provided by argument to the telety attribute.

pub fn macro_ident(&self) -> &Ident
