Enum InkItem

pub enum InkItem {
    Storage(Storage),
    Event(Event),
    ImplBlock(ItemImpl),
}

An ink! specific item.

Variants

Storage(Storage)

The ink! storage struct definition.

Event(Event)

An ink! event definition.

ImplBlock(ItemImpl)

An ink! implementation block.

Implementations

impl InkItem

pub fn is_ink_item(item: &Item) -> Result<bool, Error>

Returns true if the given syn::Item is eventually an ink! item.

Errors

If invalid or malformed ink! attributes are encountered for the given item.

impl InkItem

pub fn filter_map_storage_item(&self) -> Option<&Storage>

Returns Some if self is the ink! storage struct definition.

Otherwise, returns None.

pub fn is_storage_item(&self) -> bool

Returns true if the ink! specific item is the storage struct definition.

pub fn filter_map_event_item(&self) -> Option<&Event>

Returns Some if self is an ink! event struct definition.

Otherwise, returns None.

pub fn is_event_item(&self) -> bool

Returns true if the ink! specific item is an event struct definition.

pub fn filter_map_impl_block(&self) -> Option<&ItemImpl>

Returns Some if self is an ink! implementation block.

Otherwise, returns None.

pub fn is_impl_block(&self) -> bool

Returns true if the ink! specific item is an implementation block.

Trait Implementations

impl Debug for InkItem

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

Formats the value using the given formatter.

impl From<Event> for InkItem

fn from(event: Event) -> Self

Converts to this type from the input type.

impl From<ItemImpl> for InkItem

fn from(impl_block: ItemImpl) -> Self

Converts to this type from the input type.

impl From<Storage> for InkItem

fn from(storage: Storage) -> Self

Converts to this type from the input type.

impl PartialEq for InkItem

fn eq(&self, other: &InkItem) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ToTokens for InkItem

fn to_tokens(&self, tokens: &mut TokenStream)

We mainly implement this trait for this ink! type to have a derived Spanned implementation for it.

fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

fn into_token_stream(self) -> TokenStream

where Self: Sized,

Convert self directly into a TokenStream object.
