How do I print Rust code with syntax highlighting?

Paste your Rust code into Codeprint and select Rust as the language. Ownership keywords, lifetimes, macros, and traits are highlighted. Export via Print or PDF.

Does it highlight Rust lifetimes and generics?

Yes. Lifetime annotations ('a), generic parameters, where clauses, and trait bounds are all highlighted with distinct colors.

Can I print Rust macro definitions?

Yes. Both declarative macros (macro_rules!) and procedural macros are highlighted. Derive macros and attribute macros are also supported.

How do I handle Rust's long type signatures?

Rust type signatures can be verbose. Use landscape orientation and a smaller font size. Long lines wrap automatically while maintaining readability.

Turn Rust code into a PDF worth printing.

Keep Rust syntax colors, line numbers, and the layout you choose. Preview every page and export the PDF without uploading your code.

Rust Syntax Highlighting

Full support for Rust ownership, lifetimes, traits, derive macros, pattern matching, and error handling.

PDF Export

Export Rust files as PDF with lifetime annotations and type signatures clearly highlighted.

Customizable Layout

Adjust layout for Rust's expressive type signatures and where clauses. Landscape works well for trait implementations.

Line Numbers

Reference specific lines in Rust code for borrow checker discussions and safety reviews.

When you’d print Rust

Safety Reviews

Print Rust code for unsafe block reviews. Paper analysis helps trace ownership and lifetime relationships across functions.

Learning Rust

Print Rust examples to study ownership, borrowing, and lifetimes. Annotate printed code with ownership flow diagrams.

Systems Documentation

Include formatted Rust code in systems documentation for network stacks, parsers, and embedded firmware.

Code Reviews

Print Rust code for thorough offline review. Rust's complex type system benefits from careful paper analysis.

How it works

Step 1

Paste Your Code

Paste your Rust code into the editor or type directly. The language is auto-detected from the file extension.

Step 2

Customize Settings

Adjust font size, line numbers, columns, page orientation, and page size to match your needs.

Step 3

Print or Export PDF

Click Print to send to your printer, or PDF to download a formatted document with syntax highlighting preserved.

Why print Rust?

Rust source is easier to review when its structure survives the move from editor to page. Full support for Rust ownership, lifetimes, traits, derive macros, pattern matching, and error handling. Codeprint keeps indentation and line breaks intact, then applies a restrained syntax palette so keywords, strings, comments, and identifiers remain distinguishable in print.

A paper review creates a different reading rhythm from an IDE. You can see more of the file at once, mark a questionable branch, compare related expressions, and refer back to a precise line without opening the same toolchain. Reference specific lines in Rust code for borrow checker discussions and safety reviews.

Export Rust files as PDF with lifetime annotations and type signatures clearly highlighted. Page size, orientation, columns, and type size remain under your control, which matters when the source contains long expressions or dense blocks. It is a practical fit for safety reviews, learning rust, and technical documentation. Your source stays in your browser throughout the process.
