Expand description
I/O host interface for substrate runtime. Substrate runtime standard library as compiled when linked with Rust’s standard library.
Modules
Wasm only interface that provides functions for calling into the allocator.
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-only interface which allows for aborting the execution in case
of an unrecoverable error.
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 transaction indexing API.
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.Structs
Crossing is a helper wrapping any Encode-Decodeable type
for transferring over the wasm barrier.
Results concerning an operation to remove many keys.
Batch verification extension to register/retrieve from the externalities.
Enums
Error verifying ECDSA signature
The outcome of calling
storage_kill. Returned value is the number of storage items
removed from the backend from making the storage_kill call.Functions
Initialize tracing of sp_tracing not necessary – noop. To enable build
without std and with the
with-tracing-feature.Type Definitions
The host functions Substrate provides for the Wasm runtime environment.
Type alias for Externalities implementation used in tests.
