Add support for cargo's --profile option

[Kneelawk]

The Issue

Currently, cargo-bundle has no support for a --profile option to allow specifying custom build profiles. Cargo added support for this option in Rust 1.57.0. Adding a --profile option allows users to specify custom profiles for packaging. For example: one profile with normal release optimizations and one profile with release optimizations and link-time optimizations.

The Feature Request

The feature request is that cargo-bundle add an option --profile that takes a single argument, being the name of the custom profile to use. This will invoke the underlying cargo build command with --profile and the custom profile name. The cargo documentation specifies that the build directory used for a custom profile is target/<profile-name> where <profile-name> is the name of the profile being built.

The Pull Request

I am working on a PR to solve this issue. It should be linked once complete.

Hi there - any idea when this change will make it into a published release? Would love to use it but the current published version (v0.5.0) is over a year old, and I'd prefer not to have our build scripts pull from HEAD.

I've just published v0.6.0.
