Best use
Share one scoped Rust artifact: Borrow-checker questions.
Rust pastebin for code and compiler diagnostics
Systems code and compiler diagnostics. Pastebin.ai preserves the submitted source, adds a line-numbered reading view, and lets you choose retention and access before sharing.
Rust sharing decisions at a glance
Check the source, runtime context, and privacy risks that matter when you share Rust text.
Context to include
Name the source: Common inputs include .rs, Cargo diagnostics, and minimal crate examples. State the tool or runtime that reads them.
Details to remove
Review before upload: Inspect each Rust value, comment, path, and identifier; the checklist below names the format-specific risks.
What to include in a reviewable Rust paste
Common inputs include .rs, Cargo diagnostics, and minimal crate examples. Limit the artifact to the lines and context a recipient needs to understand its purpose.
Borrow-checker questions
Keep the Rust example limited to this review goal and its required inputs.
Compiler diagnostics
For Rust review, Name the producing tool or runtime, preserve exact source text, and include only the context another person needs to understand the artifact.
Small trait and lifetime examples
Use representative placeholders so this Rust example preserves structure without exposing live values.
A small Rust paste example
The Rust sample below uses a small, representative form of .rs, Cargo diagnostics, and minimal crate examples. Replace live values with clear placeholders while keeping the structure another reader needs.
fn first_nonempty<'a>(values: &'a [&str]) -> Option<&'a str> {
values.iter().copied().find(|value| !value.is_empty())
}Add the context a reviewer needs
Name the Rust toolchain, edition, target, relevant crate versions, features, and exact cargo command. Preserve the full primary diagnostic plus labeled spans and notes.
- Name the tool or runtime that consumes this Rust text.
- Show the command and the expected versus actual Rust result.
- Keep only the smallest Rust artifact that preserves the issue.
Review the paste before it leaves
Remove private registry URLs, repository paths, feature names that reveal internal systems, embedded tokens, application data, and sensitive panic context.
- Start a Rust review with unlisted visibility.
- Match expiry to the window for borrow-checker questions.
- Encrypt this Rust paste when readable server storage is outside the trust boundary.
Next Rust step: Code-sharing workflow adds this context: Turn a focused snippet or diagnostic into a reviewable link.
Rust paste questions
Short answers about Rust formatting, runtime context, and safer sharing.
What Rust version should I include?+
Share rustc --version, edition, target, cargo command, and relevant dependency features.
Should I paste only the highlighted error line?+
Keep the full primary diagnostic, labeled source spans, notes, and enough code for another person to compile it.
