Overview

Package query provides interfaces used to query the state of the blockchain. These interfaces abstract the underlying request/response types and provide a single method to query for a specific piece of information from the chain.

Types

type Balance added in v0.0.14 

type Balance *cosmostypes.Coin

Balance represents a pointer to a Cosmos SDK Coin used for bank balance queries. It is defined as a distinct type (not an alias) to: - Ensure clear dependency injection - Differentiate from other coin caches in the system - Maintain separation of concerns between coin-related data in the caching layer

type BlockHash added in v0.0.14 

type BlockHash []byte

BlockHash represents a byte slice used for bank balance query caches. It is defined as a distinct type (not an alias) to: - Ensure clear dependency injection - Differentiate from other byte slice caches - Maintain separation of concerns between byte slice data in caching layer

type ComponentCtxRelayMiner added in v0.1.28 

type ComponentCtxRelayMiner string

ComponentCtxRelayMiner is a type used to identify the component making the gRPC call. 

const ComponentCtxRelayMinerKey ComponentCtxRelayMiner = "component"

ComponentCtxRelayMinerKey is the context key used to identify the component calling the gRPC method using the context.WithValue method.

type Context added in v0.0.14 

type Context cosmosclient.Context

Context represents a CosmosSDK client Context used for query operations. It is defined as a distinct type (not an alias) to: - Ensure clear dependency injection - Differentiate from transaction-related contexts - Maintain separation of concerns between query and transaction operations
