PHASE 01 // LEXICAL ANALYSIS

TOKEN.001

Every quest begins with raw input -- unstructured intent, unvalidated ambition. The lexer scans the source of your purpose, breaking continuous thought into discrete tokens of meaning. Each symbol matters. Each character is weighed.

TOKEN.002

Memory safety is not a constraint -- it is a philosophy. In a world of dangling pointers and use-after-free, Rust demands you prove ownership before you act. The quest mirrors this: prove your intent before proceeding.

TOKEN.003

Zero-cost abstractions mean nothing is wasted. Every layer of design, every animation frame, every pixel of negative space serves the compilation. The foundry burns clean.

TOKEN.004

The lexer does not judge. It categorizes. It transforms chaos into a stream of tokens that downstream phases can reason about. This is the first act of transformation: raw becomes structured.

PHASE 02 // PARSING

AST.NODE.01

Tokens become trees. The parser assembles meaning from the flat stream -- building hierarchies, nesting scopes, establishing the architecture of understanding. Ambiguity is resolved. Precedence is established.

AST.NODE.02

The abstract syntax tree is a map of intention. Each node a decision point. Each branch a possibility that must be validated before execution. The parser does not execute -- it plans.

AST.NODE.03

Here the quest reveals its structure. What appeared as linear progression is actually deeply nested. Every section you have read contains sections within sections, meaning within meaning. The tree grows downward into the machine.

PHASE 03 // BORROW CHECKING

LIFETIME.01

Ownership is singular. In Rust, every value has exactly one owner. When ownership transfers, the previous holder loses access. There are no copies unless explicitly requested. This is not limitation -- this is clarity.

ERROR[E0505]

cannot move out of `quest` because it is borrowed

-- value moved here while still borrowed. The borrow checker has found a violation. References exist that outlive their referents. Memory would be corrupted. The compiler intervenes.

LIFETIME.02

Borrowing is a contract. You may read, or you may write, but never both simultaneously. The borrow checker enforces this at compile time. Runtime is too late. By the time the program runs, safety is already guaranteed.

PHASE 04 // CODE GENERATION

use std::quest::Quest;
use std::forge::Foundry;
fn main() {
    let quest = Quest::new("rust.quest");
    let foundry = Foundry::ignite();
    let tokens = quest.lex();
    let ast = tokens.parse();
    let checked = ast.borrow_check()?;
    let mut artifact = foundry
        .codegen(&checked)
        .optimize(Level::Aggressive)
        .link();
    artifact.emit("quest.complete");
    // 0 errors. 0 warnings.
}

PHASE 05 // LINKING

REF::PHASE_01

Tokens linked.

REF::PHASE_02

AST resolved.

REF::PHASE_03

Lifetimes validated.

REF::PHASE_04

Machine code emitted.

All symbols resolved. All references valid. The linker weaves disparate compilation units into a single coherent binary. What was scattered is now unified. What was abstract is now executable.

BUILD SUCCEEDED

0 errors. 0 warnings. 1 quest.
