//! Crate-local prelude (for alloc-dependent features like `Vec`)

#[cfg(feature = "std")]

Unify `alloc` and `std` cargo features This change provides a common convention for using allocator-dependent features with: #![cfg(feature = "alloc")] When available, `Vec` is imported consistently as `prelude::Vec`, which means modules that need access to `Vec` can simply do: use prelude::*; and if an allocator is available, `Vec` will be in the crate prelude. This allows all `alloc` vs `std` gating to be handled in `lib.rs`, `build.rs`, and `prelude.rs` so the rest of the codebase doesn't have to do any gating whatsoever. 2018-07-20 21:43:31 +00:00			//!
