Crate smallvec [−] [src]

Small vectors in various sizes. These store a certain number of elements inline, and fall back to the heap for larger allocations. This can be a useful optimization for improving cache locality and reducing allocator traffic for workloads that fit within the inline buffer.

no_std support

By default, smallvec depends on libstd. However, it can be configured to use the unstable liballoc API instead, for use on platforms that have liballoc but not libstd. This configuration is currently unstable and is not guaranteed to work on all versions of Rust.

To depend on smallvec without libstd, use default-features = false in the smallvec section of Cargo.toml to disable its "std" feature.
