Client

Struct Client 

Source
pub struct Client { /* private fields */ }
Expand description

Solana HyperSync client.

Thread-safe and cheap to clone (wraps an Arc).

Implementations§

Source§

impl Client

Source

pub fn new(config: ClientConfig) -> Result<Self>

Create a new client with the given configuration.

Source

pub fn new_with_agent( config: ClientConfig, user_agent: impl Into<String>, ) -> Result<Self>

Create a new client with the given configuration and a custom user agent.

This mirrors the EVM and Fuel HyperSync clients and is intended for use by language bindings (Node.js) and downstream tools that want to identify themselves to the server.

Source

pub async fn get_height(&self) -> Result<u64>

Get the current chain height (latest slot).

Source

pub async fn get_arrow(&self, query: &SolanaQuery) -> Result<QueryResponse>

Execute a single query and return Arrow data.

Source

pub async fn get_arrow_with_rate_limit( &self, query: &SolanaQuery, ) -> Result<QueryResponseWithRateLimit<QueryResponse>>

Executes query with retries and returns the response in Arrow format along with rate limit information from the server.

This is useful for consumers that want to inspect rate limit headers and implement their own rate limiting logic in external systems. Retry and back-off behaviour is identical to get_arrow: a 429 is slept out against x-ratelimit-reset and retried.

Source

pub async fn get_with_rate_limit( &self, query: &SolanaQuery, ) -> Result<QueryResponseWithRateLimit<SolanaResponse>>

Executes query with retries and returns typed Rust structs along with rate limit information from the server.

This is useful for consumers that want to inspect rate limit headers and implement their own rate limiting logic in external systems. Retry and back-off behaviour is identical to get.

Source

pub async fn collect_arrow( self: &Arc<Self>, query: SolanaQuery, config: StreamConfig, ) -> Result<QueryResponse>

Execute a query that may span many server responses, paginating automatically. Returns a single merged response.

Source

pub fn stream_arrow( self: &Arc<Self>, query: SolanaQuery, config: StreamConfig, ) -> Receiver<Result<QueryResponse>>

Stream query results with concurrent fetching and adaptive batch sizing.

Returns an mpsc receiver that yields QueryResponse items in slot order.

Source

pub async fn get(&self, query: &SolanaQuery) -> Result<SolanaResponse>

Execute a single query and return typed Rust structs.

Like Client::get_arrow, but decodes the Arrow tables into the Vec<T> shapes in crate::simple_types.

Source

pub async fn collect( self: &Arc<Self>, query: SolanaQuery, config: StreamConfig, ) -> Result<SolanaResponse>

Execute a query that may span many server responses, paginating automatically, and return typed Rust structs.

This is the typed counterpart of Client::collect_arrow.

Source

pub fn rate_limit_info(&self) -> Option<RateLimitInfo>

Returns the most recently observed rate limit information, if any.

Updated after successful and 429 query responses that contain rate limit headers.

Source

pub async fn wait_for_rate_limit(&self)

Waits until the current rate limit window resets, if the client is rate limited.

Returns immediately if:

  • No rate limit information has been observed yet
  • There is remaining quota in the current window

This method is useful for consumers who want to explicitly wait before making requests, for example when coordinating rate limits across multiple systems.
