Cryptographic utilities.
Contains the
crate::defer! macro for deferring the execution
of code until the current scope is dropped.
This helps with always executing cleanup code.Simple ECDSA secp256k1 API.
Simple Ed25519 API.
A fixed hash type.
Hashing functions.
Wrapper type for byte collections that outputs hex.
Offchain workers types
Simple sr25519 (Schnorr-Ristretto) API.
Types that should only be used for testing!
Shareable Substrate traits.
An unsigned fixed-size integer.
Macros
Executes the given code when the current scope is dropped.
Macro for creating
Maybe* marker traits.Initialize a key-value collection from array.
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
Concrete implementation of Hasher using Blake2b 256-bit hashes
Hex-serialized shim for
Vec<u8>.Fixed-size uninterpreted hash type with 20 bytes (160 bits) size.
Fixed-size uninterpreted hash type with 32 bytes (256 bits) size.
Fixed-size uninterpreted hash type with 64 bytes (512 bits) size.
Concrete implementation of Hasher using Keccak 256-bit hashes
Stores the encoded
RuntimeMetadata for the native side as opaque type.Simple blob to hold a
PeerId without committing to its format.Little-endian large integer type
256-bit unsigned integer.
Little-endian large integer type
512-bits unsigned integer.
Enums
Context for executing a call into the runtime.
A log level matching the one from
log crate.Log level filter that expresses which log levels should be filtered.
Something that is either a native or an encoded value.
A value that is never in a native representation.
This is type is useful in conjunction with
NativeOrEncoded.The void type - it cannot exist.
Constants
The maximum number of bytes that can be allocated at one time.
Traits
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.Provide a simple 4 byte identifier for a type.
