Modules

crypto	Cryptographic utilities.
ecdsa	Simple ECDSA API.
ed25519	Simple Ed25519 API.
hash	A fixed hash type.
hashing	Hashing functions.
hexdisplay	Wrapper type for byte collections that outputs hex.
offchain	Offchain workers types
sandbox	Definition of a sandbox environment.
sr25519	Simple sr25519 (Schnorr-Ristretto) API.
testing	Types that should only be used for testing!
traits	Shareable Substrate traits.
u32_trait	An u32 trait with “values” as impl’d types.
uint	An unsigned fixed-size integer.
vrf	VRF-specifc data types and helpers

Macros

impl_maybe_marker	Macro for creating Maybe* marker traits.
map	Initialize a key-value collection from array.
wasm_export_functions	Macro for exporting functions from wasm in with the expected signature for using it with the wasm executor. This is useful for tests where you need to call a function in wasm.

Structs

Blake2Hasher	Concrete implementation of Hasher using Blake2b 256-bit hashes
Bytes	Hex-serialized shim for Vec<u8>.
ChangesTrieConfiguration	Substrate changes trie configuration.
ChangesTrieConfigurationRange	Substrate changes trie configuration range.
H160	Fixed-size uninterpreted hash type with 20 bytes (160 bits) size.
H256	Fixed-size uninterpreted hash type with 32 bytes (256 bits) size.
H512	Fixed-size uninterpreted hash type with 64 bytes (512 bits) size.
KeccakHasher	Concrete implementation of Hasher using Keccak 256-bit hashes
OpaqueMetadata	Stores the encoded RuntimeMetadata for the native side as opaque type.
OpaquePeerId	Simple blob to hold a PeerId without committing to its format.
U256	Little-endian large integer type
U512	Little-endian large integer type

Enums

ExecutionContext	Context for executing a call into the runtime.
LogLevel	A log level matching the one from log crate.
NativeOrEncoded	Something that is either a native or an encoded value.
NeverNativeValue	A value that is never in a native representation. This is type is useful in conjunction with NativeOrEncoded.
Void	The void type - it cannot exist.

Traits

Hasher	Trait describing an object that can hash a slice of bytes. Used to abstract other types over the hashing algorithm. Defines a single hash method and an Out associated type with the necessary bounds.
TypeId	Provide a simple 4 byte identifier for a type.
