8-bit signed integer

Q: How deeply does Rust in Action: Systems programming concepts and techniques cover 8-bit signed integer?

Defines i8 as Q7’s one-byte representation and demonstrates scaling, clamping, derived traits, and conversions.

As explained in Rust in Action: Systems programming concepts and techniques

i8 is Rust's signed 8-bit integer type.

Rust’s i8 type stores a signed value in one byte. Here, it provides the hidden storage for Q7 fixed-point numbers representing values from −1 to 1 compactly, trading accuracy for space. section 5.5

Using i8 inside Q7

The tuple struct Q7(i8) keeps the byte field private while derived traits provide debugging, copying, and equality. Conversion clamps values at Q7(127) and Q7(−128), then scales values through the i8 representation.
