pub struct QueryClient<T> { /* private fields */ }

Available on crate feature rpc only.

Query defines the gRPC querier service.

Implementations

impl QueryClient<Channel>

pub async fn connect<D>(dst: D) -> Result<Self, Error>

where D: TryInto<Endpoint>, D::Error: Into<StdError>,

Attempt to create a new client by connecting to a given endpoint.

impl<T> QueryClient<T>

where T: GrpcService<BoxBody>, T::Error: Into<StdError>, T::ResponseBody: Body<Data = Bytes> + Send + 'static, <T::ResponseBody as Body>::Error: Into<StdError> + Send,

pub fn new(inner: T) -> Self

pub fn with_origin(inner: T, origin: Uri) -> Self

pub fn with_interceptor<F>( inner: T, interceptor: F, ) -> QueryClient<InterceptedService<T, F>>

where F: Interceptor, T::ResponseBody: Default, T: Service<Request<BoxBody>, Response = Response<<T as GrpcService<BoxBody>>::ResponseBody>>, <T as Service<Request<BoxBody>>>::Error: Into<StdError> + Send + Sync,

pub fn send_compressed(self, encoding: CompressionEncoding) -> Self

Compress requests with the given encoding.

This requires the server to support it otherwise it might respond with an error.

pub fn accept_compressed(self, encoding: CompressionEncoding) -> Self

Enable decompressing responses.

pub fn max_decoding_message_size(self, limit: usize) -> Self

Limits the maximum size of a decoded message.

Default: 4MB

pub fn max_encoding_message_size(self, limit: usize) -> Self

Limits the maximum size of an encoded message.

Default: usize::MAX

pub async fn balance( &mut self, request: impl IntoRequest<QueryBalanceRequest>, ) -> Result<Response<QueryBalanceResponse>, Status>

Balance queries the balance of a single coin for a single account.

pub async fn all_balances( &mut self, request: impl IntoRequest<QueryAllBalancesRequest>, ) -> Result<Response<QueryAllBalancesResponse>, Status>

AllBalances queries the balance of all coins for a single account.

When called from another module, this query might consume a high amount of gas if the pagination field is incorrectly set.

pub async fn spendable_balances( &mut self, request: impl IntoRequest<QuerySpendableBalancesRequest>, ) -> Result<Response<QuerySpendableBalancesResponse>, Status>

SpendableBalances queries the spendable balance of all coins for a single account.

When called from another module, this query might consume a high amount of gas if the pagination field is incorrectly set.

Since: cosmos-sdk 0.46

pub async fn spendable_balance_by_denom( &mut self, request: impl IntoRequest<QuerySpendableBalanceByDenomRequest>, ) -> Result<Response<QuerySpendableBalanceByDenomResponse>, Status>

SpendableBalanceByDenom queries the spendable balance of a single denom for a single account.

When called from another module, this query might consume a high amount of gas if the pagination field is incorrectly set.

Since: cosmos-sdk 0.47

pub async fn total_supply( &mut self, request: impl IntoRequest<QueryTotalSupplyRequest>, ) -> Result<Response<QueryTotalSupplyResponse>, Status>

TotalSupply queries the total supply of all coins.

When called from another module, this query might consume a high amount of gas if the pagination field is incorrectly set.

pub async fn supply_of( &mut self, request: impl IntoRequest<QuerySupplyOfRequest>, ) -> Result<Response<QuerySupplyOfResponse>, Status>

SupplyOf queries the supply of a single coin.

When called from another module, this query might consume a high amount of gas if the pagination field is incorrectly set.

pub async fn params( &mut self, request: impl IntoRequest<QueryParamsRequest>, ) -> Result<Response<QueryParamsResponse>, Status>

Params queries the parameters of x/bank module.

pub async fn denom_metadata( &mut self, request: impl IntoRequest<QueryDenomMetadataRequest>, ) -> Result<Response<QueryDenomMetadataResponse>, Status>

DenomsMetadata queries the client metadata of a given coin denomination.

pub async fn denoms_metadata( &mut self, request: impl IntoRequest<QueryDenomsMetadataRequest>, ) -> Result<Response<QueryDenomsMetadataResponse>, Status>

DenomsMetadata queries the client metadata for all registered coin denominations.

pub async fn denom_owners( &mut self, request: impl IntoRequest<QueryDenomOwnersRequest>, ) -> Result<Response<QueryDenomOwnersResponse>, Status>

DenomOwners queries for all account addresses that own a particular token denomination.

When called from another module, this query might consume a high amount of gas if the pagination field is incorrectly set.

Since: cosmos-sdk 0.46

pub async fn send_enabled( &mut self, request: impl IntoRequest<QuerySendEnabledRequest>, ) -> Result<Response<QuerySendEnabledResponse>, Status>

SendEnabled queries for SendEnabled entries.

This query only returns denominations that have specific SendEnabled settings. Any denomination that does not have a specific setting will use the default params.default_send_enabled, and will not be returned by this query.

Since: cosmos-sdk 0.47
