This is needed for cargo to use proxies set by bitbake. It is important for devtooled builds which does not use vendored sources.

## 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

|

|
|
# for cross compilation, so tell it we know better than it.

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