Struct AsyncGrpcCall 

pub struct AsyncGrpcCall<Response, Error = Error> { /* private fields */ }

A call of the grpc method.

Allows setting additional context for request before awaiting the call.

let balance = client.get_balance(addr, "utia")
    .metadata("x-token", "your secret token")?
    .block_height(12345)
    .await?;

Implementations

impl<Response, Error> AsyncGrpcCall<Response, Error>

pub fn metadata(self, key: &str, val: &str) -> Result<Self, MetadataError>

Append an ascii metadata to the grpc request.

pub fn metadata_bin(self, key: &str, val: &[u8]) -> Result<Self, MetadataError>

Append a binary metadata to the grpc request.

Keys for binary metadata must have -bin suffix.

pub fn metadata_map(self, metadata: MetadataMap) -> Self

Append a metadata map to the grpc request.

pub fn block_height(self, height: u64) -> Self

Performs the state queries at the specified height, unless node pruned it already.

Appends x-cosmos-block-height metadata entry to the request.
