Functions
pub fn binary_to_term(binary: BitString) -> Result(Dynamic, Nil)
pub external fn erlang_timestamp() -> #(Int, Int, Int)
Returns the current OS system time as a tuple of Ints
http://erlang.org/doc/man/os.html#timestamp-0
pub external fn get_line(
prompt: String,
) -> Result(String, GetLineError)
Reads a line from standard input with the given prompt.
Example
> get_line("Language: ")
// -> Language: <- gleam
Ok("gleam\n")
pub external fn rescue(fn() -> a) -> Result(a, Crash)
Gleam doesn’t offer any way to raise exceptions, but they may still occur due to bugs when working with unsafe code, such as when calling Erlang function.
This function will catch any error thrown and convert it into a result rather than crashing the process.
pub external fn system_time(TimeUnit) -> Int
Returns the current OS system time.

pub external fn term_to_binary(a) -> BitString
pub fn unsafe_binary_to_term(
binary: BitString,
) -> Result(Dynamic, Nil)
