Expand description

View of block extrinsics restricted to signed transactions.

Implementations§

Source§

impl BlockWithTx

Source

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

Builds a signed transaction view for the given block.

Only signed extrinsics will be surfaced; unsigned extrinsics produce an Error when decoding.

Source

pub async fn get<T: HasHeader + Decode>( &self, extrinsic_id: impl Into<HashStringNumber>, ) -> Result<Option<BlockTransaction<T>>, Error>

Fetches a signed transaction by id.

§Returns
  • Ok(Some(BlockTransaction<T>)) when the extrinsic exists and carries a signature.
  • Ok(None) when no extrinsic matches the identifier.
  • Err(Error) when the extrinsic exists but is unsigned or cannot be decoded as T.
Source

pub async fn first<T: HasHeader + Decode>( &self, opts: BlockExtOptionsSimple, ) -> Result<Option<BlockTransaction<T>>, Error>

Returns the first matching signed transaction.

Unsigned extrinsics encountered during decoding produce an Error.

Source

pub async fn last<T: HasHeader + Decode>( &self, opts: BlockExtOptionsSimple, ) -> Result<Option<BlockTransaction<T>>, Error>

Returns the last matching signed transaction.

Return semantics mirror BlockWithTx::first, but returns the final matching transaction.

Source

pub async fn all<T: HasHeader + Decode>( &self, opts: BlockExtOptionsSimple, ) -> Result<Vec<BlockTransaction<T>>, Error>

Returns every matching signed transaction.

Decoding stops early with an Error if any extrinsic lacks a signature or fails to decode as T.

Source

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

Counts matching signed transactions.

Source

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

Checks whether any signed transaction matches the filters.

Source

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

Controls retry behaviour for signed-transaction lookups: Some(true) forces retries, Some(false) disables them, and None keeps the client’s default.

Source

pub fn should_retry_on_error(&self) -> bool

Returns true when signed transaction lookups retry after RPC errors.
