[−][src]Crate alloc

A shim crate for to import items of alloc crate ergonomically.

Usage

Add this to your Cargo.toml:

[dependencies]
alloc-shim = { version = "0.2.1" }

Set the features so that std depends on alloc-shim/std, and alloc depends on alloc-shim/alloc:

[features]
std = ["alloc-shim/std"]
alloc = ["alloc-shim/alloc"]

Now, you can use alloc-shim:

#[cfg(any(feature = "alloc", feature = "std"))]
use alloc::prelude::v1::*; // And more...

The current version of alloc-shim requires Rust 1.31 or later.
