Crate solana_sdk

The Miraland host and client SDK.

This is the base library for all off-chain programs that interact with Miraland or otherwise operate on Miraland data structures. On-chain programs instead use the miraland-program crate, the modules of which are re-exported by this crate, like the relationship between the Rust core and std crates. As much of the functionality of this crate is provided by miraland-program, see that crate’s documentation for an overview.

Many of the modules in this crate are primarily of use to the Miraland runtime itself. Additional crates provide capabilities built on miraland-sdk, and many programs will need to link to those crates as well, particularly for clients communicating with Miraland nodes over RPC.

Such crates include:

• miraland-client - For interacting with a Miraland node via the JSON-RPC API.
• miraland-cli-config - Loading and saving the Miraland CLI configuration file.
• miraland-clap-utils - Routines for setting up the CLI using clap, as used by the Miraland CLI. Includes functions for loading all types of signers supported by the CLI.
