OmnipotentEntity@beehaw.orgtoRust@programming.dev•Making Rust binaries smaller by default
4·
8 months agoAs mentioned in the article, this concerns release mode, which already does not have symbols by default for user code. It does have symbols for the standard library code, however, due to how the binaries for the standard library are shipped (i.e. with symbols only). This change simply also removes standard library symbols.
If you need symbols, you can use default debugging build, or if you need both compiler optimizations and debugging symbols you can create a custom profile that inherets from release with debug = true. The second you already need to do to get full debugging symbols right now, so this isn’t really much of a change from a workflow standpoint.
Yeah, definitely :)
The default dev profile is defined as:
[profile.dev] opt-level = 0 debug = true split-debuginfo = '...' # Platform-specific. strip = "none" debug-assertions = true overflow-checks = true lto = false panic = 'unwind' incremental = true codegen-units = 256 rpath = false
You can find more information in the cargo book page on profiles
