Rust debug
Learn how to use the debug trait to format and print values in a debugging context. See examples, methods, and implementations of the trait for various types. The rust compiler produces native binaries with native debug info (symbol) information, so any native debugger will do. That means gdb and lldb, or the windows debuggers (windbg or just visual studio) if youre using the msvc abi version of rust.
Many developers choose to debug their code in visual studio code because it is free and feels snappy to use on most hardware. Lets see how we can get set up with rust on visual studio code for debugging! Jump ahead what should we debug our rust code with?learn how to set up and use rust with visual studio code, a powerful programming language for systems programming. The rust-analyzer extension provides intellisense, semantic syntax highlighting, code navigation, and more features for rust development. Learn how to use gdb, lldb, windbgcdb, and other tools to debug rust code.
Find out how the rust compiler generates and consumes dwarf, codeviewpdb, and natvis formats for debugging information. I typically use rust-gdb (which pretty prints rust objects, but it is similar to rust-lldb) on the binary in targetdebugdeps like you mentioned. On linux, you can confirm the binary youre debugging has debug symbols by running file pathtobin and check for debuginfo, not stripped. All types which want to use stdfmt formatting traits require an implementation to be printable.
Automatic implementations are only provided for types such as in the std library. Трейт debug позволяет вывести данные на консоль в удобном для разработчиков виде. Все типы могут выводить (автоматически создавать, derive) реализацию fmtdebug. .
