rust - 我可以只为没有包的代码包含调试信息吗？

Question

有了包含的调试信息，我的二进制文件就变成了 400 MB 左右。发生这种情况是因为 Rust 包含所有依赖项的调试信息。有什么方法可以只为我的代码包含调试信息吗？

[package]
name = "app"
version = "0.7.1"
edition = "2018"

[dependencies]
actix = "*"
actix-web = {version = "1.0", features = ["ssl"]}
...
tokio-core = "*"
tokio = "*"

[profile.release]
debug = true

Answer 1

编辑:此功能现已稳定，无需 cargo-features list key 即可在稳定的工具链上使用。此功能记录在案 in the Cargo reference .

如果您愿意通过夜间工具链使用不稳定的 cargo 功能，这可以通过 cargo profile dependencies 实现。功能，像这样:

cargo-features = ["profile-overrides"]

[package]
name = "app"
version = "0.7.1"
edition = "2018"

[dependencies]
actix = "*"
actix-web = {version = "1.0", features = ["ssl"]}
...
tokio-core = "*"
tokio = "*"

[profile.release]
debug = true

// disable debug symbols for all packages except this one
[profile.release.package."*"]
debug = false
