Enum ImplItem

pub enum ImplItem {
    Constructor(Constructor),
    Message(Message),
    Other(ImplItem),
}

An item within an ink! implementation block.

Can be either

• an ink! ir::Constructor
• an ink! ir::Message
• or any other non-ink! item.

Note

Based on syn::ImplItem with special variants for ink! impl items.

Variants

Constructor(Constructor)

A #[ink(constructor)] marked inherent function.

Message(Message)

A #[ink(message)] marked method.

Other(ImplItem)

Any other implementation block item.

Implementations

impl ImplItem

pub fn is_message(&self) -> bool

Returns true if the impl block item is an ink! message.

pub fn filter_map_message(&self) -> Option<&Message>

Returns Some if self is an ink! message.

Otherwise, returns None.

pub fn is_constructor(&self) -> bool

Returns true if the impl block item is an ink! message.

pub fn filter_map_constructor(&self) -> Option<&Constructor>

Returns Some if self is an ink! constructor.

Otherwise, returns None.

pub fn is_other_item(&self) -> bool

Returns true if the impl block item is a non ink! specific item.

pub fn filter_map_other_item(&self) -> Option<&ImplItem>

Returns Some if self is a not an ink! specific item.

Otherwise, returns None.

Trait Implementations

impl Debug for ImplItem

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

Formats the value using the given formatter.

impl PartialEq for ImplItem

fn eq(&self, other: &ImplItem) -> 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 ImplItem

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.

impl TryFrom<ImplItem> for ImplItem

type Error = Error

The type returned in the event of a conversion error.

fn try_from(impl_item: ImplItem) -> Result<Self, Self::Error>

Performs the conversion.
