Rust puts its unitests inside its main source files, unlike most

|
languages that put them in external files. This means that normally
|
|
you have to define two separate targets with basically the same
|
|
arguments to get tests:
|
|
|
|
```meson
|
|
rust_lib_sources = [...]
|
|
rust_lib = static_library(
|
|
'rust_lib',
|
|
rust_lib_sources,
|

rust_lib_sources,

test(
|
|
'rust_lib_test',
|
|
rust_lib_test,
|
|
protocol : 'rust',
|
|
)
|
|
```
|
|
|
|
This is all fine, but not very DRY. This method makes it much easier
|
|
to define rust tests:
|
|
|
|
```meson
|
|
rust = import('unstable-rust')
|
|
|
|
rust_lib = static_library(
|

'rust_lib',
