Crate stet_core 

Core type system, storage, tokenizer, and runtime context for the stet PostScript interpreter.

This crate provides the PostScript VM building blocks: PsObject / PsValue, the interpreter Context (operand / execution / dictionary stacks, graphics state, VM stores), the arena- backed StringStore / ArrayStore / DictStore with copy-on-write save/restore semantics, the NameTable name-interning system, the PS tokenizer, the OutputDevice trait, file handles, and the error hierarchy.

Most users should use the stet facade crate rather than depending on stet-core directly. Pull this crate in only when you need to build alternative PS-interpreter tooling or implement a custom OutputDevice.

See the Architecture Guide for how this crate fits into the broader workspace.

Modules
