decode_to_slice requires a global_allocator to be configured

[leighmcculloch]

I'm using v2.0.0, with the following Cargo.toml config:

[dependencies]
base64-url = {version= "2.0.0", default-features = false}

And the code is using this one function:

base64_url::decode_to_slice(...)

When I use this in a build that has no global_allocator, I see the following error:

error: no global memory allocator found but one is required; link to std or add `#[global_allocator]` to a static item that implements the GlobalAlloc trait

The alloc feature of the base64 crate is always enabled. You can try to use the base64 crate directly without activate the alloc feature.

base64::engine::general_purpose::URL_SAFE_NO_PAD.decode_slice(input, output)
