Auto merge of #153025 - joboet:bytestr_precision_display, r=Mark-Simulacrum

core: respect precision in `ByteStr` `Display`

Fixes rust-lang/rust#153022.

`ByteStr`'s `Display` implementation didn't respect the precision parameter. Just like `Formatter::pad`, this is fixed by counting off the characters in the string and truncating after the requested length – with the added complication that the `ByteStr` needs to be divided into chunks first. By including a fast path that avoids counting the characters when no parameters were specified this should also fix the performance regressions caused by rust-lang/rust#152865.

Website | Getting started | Learn | Documentation | Contributing

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.

Why Rust?

  • Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.

  • Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.

  • Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).

Quick Start

Read “Installation” from The Book.

Installing from Source

If you really want to install from source (though this is not recommended), see INSTALL.md.

Getting Help

See https://www.rust-lang.org/community for a list of chat platforms and forums.

Contributing

See CONTRIBUTING.md.

For a detailed explanation of the compiler's architecture and how to begin contributing, see the rustc-dev-guide.
