Expand description

Data structures to operate on contract memory during contract execution.

These definitions are useful since we are operating in a no_std environment and should be used by all ink! crates instead of directly using std or alloc crates. If needed we shall instead enhance the exposed types here.

The ink_prelude crate guarantees a stable interface between std and no_std mode.


A module for working with borrowed data.

A pointer type for heap allocation.

Collection types.

A UTF-8–encoded, growable string.

A contiguous growable array type with heap-allocated contents, written Vec<T>.


Creates a String using interpolation of runtime expressions.

Creates a Vec containing the arguments.
