The Rust SGX SDK Standard Library
The Rust SGX standard library is the foundation of portable Rust SGX SDK,
a set of minimal and battle-tested shared abstractions for the Rust SGX
ecosystem. Similar to Rust’s libstd, it offers core types, like Vec<T> and
Option<T>, library-defined operations on language
primitives, standard macros, [I/O] and
[multithreading], among [many other things][other].
std is available to all Rust crates by default, just as if each one
contained an extern crate sgx_tstd as std; import at the [crate root]. Therefore the
standard library can be accessed in [use] statements through the path
std, as in [use std::env], or in expressions through the absolute path
::std, as in [::std::env::args].
