Expand description

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

Modules

  • allocator
    Wasm only interface that provides functions for calling into the allocator.
  • crypto
    Interfaces for working with crypto related types from within the runtime.
  • default_child_storage
    Interface for accessing the child storage for default child trie, from within the runtime.
  • hashing
    Interface that provides functions for hashing with different algorithms.
  • logging
    Interface that provides functions for logging from within the runtime.
  • misc
    Interface that provides miscellaneous functions for communicating between the runtime and the node.
  • offchain
    Interface that provides functions to access the offchain functionality.
  • offchain_index
    Interface that provides functions to access the Offchain DB.
  • panic_handler
    WASM-only interface which allows for aborting the execution in case of an unrecoverable error.
  • storage
    Interface for accessing the storage from within the runtime.
  • transaction_index
    Interface that provides transaction indexing API.
  • trie
    Interface that provides trie related functionality.
  • wasm_tracing
    Interface to provide tracing facilities for wasm. Modelled after tokios tracing-crate interfaces. See sp-tracing for more information.

Structs

  • Crossing
    Crossing is a helper wrapping any Encode-Decodeable type for transferring over the wasm barrier.
  • MultiRemovalResults
    Results concerning an operation to remove many keys.
  • UseDalekExt
    Extension to signal to [crypt::ed25519_verify] to use the dalek crate.
  • VerificationExt
    Batch verification extension to register/retrieve from the externalities.

Enums

  • EcdsaVerifyError
    Error verifying ECDSA signature
  • KillStorageResult
    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

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