Struct EventDetails 

pub struct EventDetails<T: Config> { /* private fields */ }

The event details.

Implementations

impl<T: Config> EventDetails<T>

pub fn phase(&self) -> Phase

When was the event produced?

pub fn index(&self) -> u32

What index is this event in the stored events for this block.

pub fn pallet_index(&self) -> u8

The index of the pallet that the event originated from.

pub fn variant_index(&self) -> u8

The index of the event variant that the event originated from.

pub fn pallet_name(&self) -> &str

The name of the pallet from whence the Event originated.

pub fn variant_name(&self) -> &str

The name of the event (ie the name of the variant that it corresponds to).

pub fn event_metadata(&self) -> EventMetadataDetails<'_>

Fetch details from the metadata for this event.

pub fn bytes(&self) -> &[u8]

Return all of the bytes representing this event, which include, in order:

• The phase.
• Pallet and event index.
• Event fields.
• Event Topics.

pub fn field_bytes(&self) -> &[u8]

Return the bytes representing the fields stored in this event.

pub fn field_values(&self) -> Result<Composite<u32>, Error>

Decode and provide the event fields back in the form of a scale_value::Composite type which represents the named or unnamed fields that were present in the event.

pub fn as_event<E: StaticEvent>(&self) -> Result<Option<E>, Error>

Attempt to decode these EventDetails into a type representing the event fields. Such types are exposed in the codegen as pallet_name::events::EventName types.

pub fn as_root_event<E: DecodeAsType>(&self) -> Result<E, Error>

Attempt to decode these EventDetails into a root event type (which includes the pallet and event enum variants as well as the event fields). A compatible type for this is exposed via static codegen as a root level Event type.

pub fn topics(&self) -> &[HashFor<T>]

Return the topics associated with this event.

Trait Implementations

impl<T: Clone + Config> Clone for EventDetails<T>

fn clone(&self) -> EventDetails<T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug + Config> Debug for EventDetails<T>

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

Formats the value using the given formatter.
