Struct Event

pub struct Event { /* private fields */ }

A checked ink! event with its configuration.

Implementations

impl Event

pub fn new(config: TokenStream2, item: TokenStream2) -> Result<Self, Error>

Returns Ok if the input matches all requirements for an ink! event.

pub fn item(&self) -> &ItemStruct

Returns the event definition .

pub fn anonymous(&self) -> bool

Returns if the event is marked as anonymous, if true then no signature topic is generated or emitted.

pub fn signature_topic_hex(&self) -> Option<&str>

Return manually specified signature topic hash.

Note

Conflicts with anonymous

pub fn get_cfg_attrs(&self, span: Span) -> Vec<TokenStream2>

Returns a list of cfg attributes if any.

Trait Implementations

impl Debug for Event

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 PartialEq for Event

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

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<ItemStruct> for Event

type Error = Error

The type returned in the event of a conversion error.

fn try_from(item_struct: ItemStruct) -> Result<Self, Self::Error>

Performs the conversion.
