Modules

bounded_btree_map

Traits, types and structs to support a bounded BTreeMap.

Traits, types and structs to support putting a bounded vector into storage, as a raw value, map or a double map.

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

bounded_btree_map

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.

generate_feature_enabled_macro

Generates a macro for checking if a certain feature is enabled.

impl_maybe_marker

Macro for creating Maybe* marker traits.

Initialize a key-value collection from array.

parameter_types

Create new implementations of the Get trait.

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.

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.

Enums

ExecutionContext

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

MAX_POSSIBLE_ALLOCATION

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
