We use cargo vendor to generate a .cargo/config file and the vendor directory. Vendoring allows us to lock our dependencies and to modify them easily from the top level Cargo.toml. We vendor all dependencies, including the crates.io ones, which allows for network isolated builds. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

# cfg-if

[Documentation](https://docs.rs/cfg-if)
|
|
|
|
A macro to ergonomically define an item depending on a large number of #[cfg]
|
|
parameters. Structured like an if-else chain, the first matching branch is the
|
|
item that gets emitted.
|
|
|
|
```toml
|
|
[dependencies]
|
|
cfg-if = "0.1"
|
|
```
|
|
|
|
## Example
|
|
|
|
```rust
|
|
#[macro_use]
|
|
extern crate cfg_if;
|
|
|
|
cfg_if! {
|
|
if #[cfg(unix)] {
|
|
fn foo() { /* unix specific functionality */ }
|
|
} else if #[cfg(target_pointer_width = "32")] {
|
|
fn foo() { /* non-unix, 32-bit functionality */ }
|
|
} else {
|
|
fn foo() { /* fallback implementation */ }
|
|
}
|
|
}
|
|
|
|
fn main() {
|
|
foo();
|
|
}
|
|
```
