Struct QueryMethods 

pub struct QueryMethods { /* private fields */ }

Methods for issuing circles_query requests and decoding the tabular response.

Includes a pager that adds stable ordering (block/tx/log/timestamp) and extracts cursors for streaming.

Implementations

impl QueryMethods

pub fn new(client: RpcClient) -> Self

Create a new accessor for circles_query RPCs.

pub async fn circles_query<TRow>( &self, params: QueryParams, ) -> Result<Vec<TRow>>

where TRow: DeserializeOwned + Send + Sync + Debug + Unpin + 'static,

Direct circles_query invocation returning decoded rows.

pub async fn paged_query<TRow>( &self, params: PagedQueryParams, ) -> Result<PagedResult<TRow>>

where TRow: DeserializeOwned + Serialize + Clone + Send + Sync + Debug + Unpin + 'static,

Convenience wrapper for paged queries using the circles_query method. Note: The underlying backend expects QueryParams; we translate from the higher-level PagedQueryParams struct.

pub fn decode_rows<TRow>( &self, columns: Vec<String>, rows: Vec<Vec<Value>>, ) -> Result<Vec<TRow>>

where TRow: DeserializeOwned,

pub fn decode_row<TRow>( &self, columns: &[String], row: Vec<Value>, ) -> Result<TRow>

where TRow: DeserializeOwned,

pub fn extract_cursors( &self, columns: &[String], rows: &[Vec<Value>], cursor_columns: &[CursorColumn], ) -> Vec<Cursor>

Trait Implementations

fn clone(&self) -> QueryMethods

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryMethods

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

Formats the value using the given formatter.
