Struct ExtrinsicMetadata

pub struct ExtrinsicMetadata { /* private fields */ }

Metadata for the extrinsic type.

Implementations

impl ExtrinsicMetadata

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

Which extrinsic versions are supported.

pub fn transaction_extensions_by_version( &self, version: u8, ) -> Option<impl Iterator<Item = TransactionExtensionMetadata<'_>>>

The extra/additional information associated with the extrinsic.

pub fn transaction_extension_version_to_use_for_encoding(&self) -> u8

When constructing a v5 extrinsic, use this transaction extensions version.

pub fn transaction_extensions_to_use_for_encoding( &self, ) -> impl Iterator<Item = TransactionExtensionMetadata<'_>>

An iterator of the transaction extensions to use when encoding a transaction. Basically equivalent to self.transaction_extensions_by_version(self.transaction_extension_version_to_use_for_encoding()).unwrap()

pub fn transaction_extension_version_to_use_for_decoding(&self) -> u8

When presented with a v4 extrinsic that has no version, treat it as being this version.
