@ -94,6 +94,14 @@ To do that add the following to your Cargo.toml:
serde = { version = "1.0.27", default-features = false } serde = { version = "1.0.27", default-features = false }
``` ```
Also, note that this implies that there is no memory allocator enabled by
default. Therefore, if you have access to heap memory and want to use modules
from the standard library such as String, Vec or similar you need to explicitly
define which memory allocator to use. There are a number of different memory
allocators available for that, for example
[alloc](https://doc.rust-lang.org/nightly/alloc/index.html) that the standard
library in Rust is using.
