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.

    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
