Modules§

bounded_btree_map
Traits, types and structs to support a bounded BTreeMap.
bounded_vec
Traits, types and structs to support putting a bounded vector into storage, as a raw value, map or a double map.
const_hex2array
Provides a const function for converting a hex string to a u8 array at compile time, when used in the proper context.
crypto
Cryptographic utilities.
crypto_bytes
Generic byte array which can be specialized with a marker type.
defer
Contains the crate::defer! macro for deferring the execution of code until the current scope is dropped. This helps with always executing cleanup code.
ecdsa
Simple ECDSA secp256k1 API.
ed25519
Simple Ed25519 API.
hash
A fixed hash type.
hexdisplay
Wrapper type for byte collections that outputs hex.
offchain
Offchain workers types
paired_crypto
API for using a pair of crypto schemes together.
proof_of_possession
Utilities for proving possession of a particular public key
sr25519
Simple sr25519 (Schnorr-Ristretto) API.
testing
Types that should only be used for testing!
traits
Shareable Substrate traits.
uint
An unsigned fixed-size integer.

Macros§

bounded_btree_map
Build a bounded btree-map from the given literals.
bounded_vec
Build a bounded vec from the given literals.
defer
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.
hex2array
Provides a const array from given string literal.
impl_maybe_marker
Macro for creating Maybe* marker traits.
impl_maybe_marker_std_or_serde
Macro for creating Maybe* marker traits.
map
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.

Traits§

Get
A trait for querying a single value from a type.
