Browse source 
We can mention that constants are declared with 'const' in one line.
Don't need an entire section.

written between double quotes, allow the same escape sequences. Rust strings
may contain newlines.
## Constants
Compile-time constants are declared with `const`. A constant may have any
scalar type (for example, integer or float). Other allowable constant types
are fixed-length vectors, static strings (more on this later), and
structs. Constants may be declared in any scope and may refer to other
constants. The compiler does not infer types for constants, so constants must
always be declared with a type annotation. By convention, they are written in
all capital letters.

// Scalars can be constants
const MY_PASSWORD: int = 12345;
// Scalar constants can be combined with other constants
const MY_DOGGIES_PASSWORD: int = MY_PASSWORD + 1;
// Fixed-length vectors
const MY_VECTORY_PASSWORD: [int * 5] = [1, 2, 3, 4, 5];
// Static strings
const MY_STRINGY_PASSWORD: &static/str = "12345";
// Structs
struct Password { value: int }
const MY_STRUCTY_PASSWORD: Password = Password { value: MY_PASSWORD };

## Operators
Rust's set of operators contains very few surprises. Arithmetic is done with
