Recent versions of cargo support always showing the progress indicator. By default the progress indicator is hidden if the output is not a tty. For bitbake builds, the output is redirected to a file and not a tty. However, if we tell cargo to always show the progress indicator, bitbake can parse it and will show the user how the rust build is progressing.

## Purpose:
|
|
## This class is to support building with cargo. It
|
|
## must be different than cargo.bbclass because Rust
|
|
## now builds with Cargo but cannot use cargo.bbclass
|
|
## due to dependencies and assumptions in cargo.bbclass
|
|
## that Rust & Cargo are already installed. So this
|
|
## is used by cargo.bbclass and Rust
|
|
##
|
|
|
|
# add crate fetch support

|

# cross compiling unless this is defined. We set up pkg-config appropriately
|
|
# for cross compilation, so tell it we know better than it.

# Don't instruct cargo to use crates downloaded by bitbake. Some rust packages,
