Struct BlockWithRawExt 

pub struct BlockWithRawExt { /* private fields */ }

View of block extrinsics as raw payloads with associated metadata.

Implementations

impl BlockWithRawExt

pub fn new(client: Client, block_id: impl Into<HashStringNumber>) -> Self

Builds a raw extrinsic view for the given block.

The block_id may be a height or hash; conversions happen lazily when RPCs are executed.

pub async fn get( &self, extrinsic_id: impl Into<HashStringNumber>, encode_as: EncodeSelector, ) -> Result<Option<BlockRawExtrinsic>, Error>

Finds a specific extrinsic and returns it in the requested format.

Returns

• Ok(Some(BlockRawExtrinsic)) when the extrinsic is found.
• Ok(None) when no extrinsic matches the provided identifier.
• Err(Error) when decoding the identifier fails or the RPC call errors.

pub async fn first( &self, opts: BlockExtOptionsExpanded, ) -> Result<Option<BlockRawExtrinsic>, Error>

Returns the first matching extrinsic, if any.

Returns

• Ok(Some(BlockRawExtrinsic)) with metadata and optional payload.
• Ok(None) when nothing matches the provided filters.
• Err(Error) on RPC failures or when the block identifier cannot be decoded.

pub async fn last( &self, opts: BlockExtOptionsExpanded, ) -> Result<Option<BlockRawExtrinsic>, Error>

Returns the last matching extrinsic, if any.

Return semantics mirror BlockWithRawExt::first, but the final matching element is returned.

pub async fn all( &self, opts: BlockExtOptionsExpanded, ) -> Result<Vec<BlockRawExtrinsic>, Error>

Returns all matching extrinsics.

The resulting vector may be empty when no extrinsics satisfy the filters.

pub async fn count(&self, opts: BlockExtOptionsExpanded) -> Result<usize, Error>

Counts matching extrinsics without fetching the payloads.

Equivalent to self.all(opts).await.map(|v| v.len()) but avoids transferring payload bytes.

pub async fn exists(&self, opts: BlockExtOptionsExpanded) -> Result<bool, Error>

Checks whether at least one extrinsic matches.

pub fn set_retry_on_error(&mut self, value: Option<bool>)

Controls retry behaviour for fetching raw extrinsics: Some(true) forces retries, Some(false) disables them, and None keeps the client’s default.

pub fn should_retry_on_error(&self) -> bool

Returns true when raw extrinsic lookups retry after RPC errors.
