Struct ink_lang_ir::Event

pub struct Event {
    pub anonymous: bool,
    // some fields omitted
}

An ink! event struct definition.

Example

#[ink(event)]
pub struct Transaction {
    #[ink(topic)]
    from: AccountId,
    #[ink(topic)]
    to: AccountId,
    value: Balance,
}

Fields

anonymous: bool

Implementations

impl Event

pub fn ident(&self) -> &Ident

Returns the identifier of the event struct.

pub fn fields(&self) -> EventFieldsIter<'_>

Returns an iterator yielding all the #[ink(topic)] annotated fields of the event struct.

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

Returns all non-ink! attributes.

Trait Implementations

impl Debug for Event

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

Formats the value using the given formatter.

impl Eq for Event

impl From<Event> for InkItem

fn from(event: Event) -> Self

Performs the conversion.

impl PartialEq<Event> for Event

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl StructuralEq for Event

impl StructuralPartialEq for Event

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

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.
