Crate sp_io

Expand description

I/O host interface for substrate runtime. Substrate runtime standard library as compiled when linked with Rust’s standard library.

Modules

Interfaces for working with crypto related types from within the runtime.

Interface for accessing the child storage for default child trie, from within the runtime.

Interface that provides functions for hashing with different algorithms.

Interface that provides functions for logging from within the runtime.

Interface that provides miscellaneous functions for communicating between the runtime and the node.

Interface that provides functions to access the offchain functionality.

Interface that provides functions to access the Offchain DB.

Wasm host functions for managing tasks.

Wasm-only interface that provides functions for interacting with the sandbox.

Interface for accessing the storage from within the runtime.

Interface that provides trie related functionality.

Interface to provide tracing facilities for wasm. Modelled after tokios tracing-crate interfaces. See sp-tracing for more information.

Crossing is a helper wrapping any Encode-Decodeable type for transferring over the wasm barrier.

Batch verification extension to register/retrieve from the externalities.

Error verifying ECDSA signature

Initialize tracing of sp_tracing not necessary – noop. To enable build without std and with the with-tracing-feature.

The host functions Substrate provides for the Wasm runtime environment.

Type alias for Externalities implementation used in tests.
