[−][src]Crate alloc
A shim crate for to import items of alloc crate ergonomically.
Usage
Add this to your Cargo.toml
:
[dependencies]
alloc-shim = "0.3.0"
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"]
Add this to your crate root (lib.rs or main.rs):
#![cfg_attr(feature = "alloc", feature(alloc))]
Now, you can use alloc-shim:
#[cfg(any(feature = "alloc", feature = "std"))] use alloc::prelude::*; // And more...
The current version of alloc-shim requires Rust 1.31 or later.
