Lowest-abstraction level for the Substrate runtime: just exports useful primitives from std or client/alloc to be used with any code that depends on the runtime. Substrate runtime standard library as compiled when linked with Rust’s standard library.
Memory allocation APIs.
This module contains the
Any trait, which enables dynamic typing
'static type through runtime reflection. It also contains the
Provider trait and accompanying API, which enable trait objects to provide
data based on typed requests, an alternate form of runtime reflection.
A module for working with borrowed data.
A pointer type for heap allocation.
Shareable mutable containers.
Clone trait for types that cannot be ‘implicitly copied’.
Functionality for ordering and comparison.
Traits for conversions between types.
Default trait for types which may have meaningful default values.
Utilities for formatting and printing
Generic hashing support.
Composable external iteration.
Primitive traits and types representing basic properties of types.
Basic functions for dealing with memory.
Additional functionality for numerics.
Prelude of common useful imports.
Manually manage memory through raw pointers.
Single-threaded reference-counting pointers. ‘Rc’ stands for ‘Reference Counted’.
Error handling with the
A dynamically-sized view into a contiguous sequence,
Unicode string slices.
Useful synchronization primitives.
A contiguous growable array type with heap-allocated contents, written
Feature gate some code that should only be run when
std feature is enabled.
Initialize a key-value collection from array.
A target for
core::write! macro - constructs a string in memory.
