Have you ever tried to compile a helloworld Rust program in --release mode? If yes, have you seen its binary size? Suffice to say, it’s not exactly small. Or at least it wasn’t small until recently. This post details how I found about the issue and my attempt to fix it in Cargo.

    In fact, this new default will be used for any profile which does not enable debuginfo anywhere in its dependency chain, not just for the release profile.

    This is the sentence that tripped me up. But on rereading I’m assuming the debug profile does enable this.

      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
