Modules

Bounded collection types.

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

Build a bounded btree-map from the given literals.

Build a bounded vec from the given literals.

Executes the given code when the current scope is dropped.

Macro for creating Maybe* marker traits.

Initialize a key-value collection from array.

Create new implementations of the Get trait.

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.

Const getter for a basic type.

Implement Get by returning Default for any type that implements Default.

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.

The void type - it cannot exist.

Constants

The maximum number of bytes that can be allocated at one time.

Traits

A trait for querying a single value from a type.

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.

Try and collect into a collection C.

Provide a simple 4 byte identifier for a type.

A trait for querying a single value from a type defined in the trait.

Functions
