Struct subxt::events::EventDetails

pub struct EventDetails { /* private fields */ }

The event details.

Implementations

impl EventDetails

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) -> &EventMetadata

Fetch 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<TypeId>, 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>, CodecError>

Attempt to decode these EventDetails into a specific static event. This targets the fields within the event directly. You can also attempt to decode the entirety of the event type (including the pallet and event variants) using EventDetails::as_root_event().

pub fn as_root_event<E: Decode>(&self) -> Result<E, CodecError>

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.
