yang2-rs
Rust bindings for the libyang2 library.
For raw FFI bindings for libyang2, see libyang2-sys.
Cargo.toml
[dependencies]
yang2 = "0.1"
Design Goals
- Provide high-level bindings for libyang2 using idiomatic Rust
- Leverage Rust's ownership system to detect API misuse problems at compile time
- Automatic resource management
- Zero-cost abstractions
Example
A basic example that parses and validates JSON instance data, and then converts
it to the XML format:
use std::fs::File;
use yang2::context::{Context, ContextFlags};
use yang2::data::{
Data, DataFormat, DataParserFlags, DataPrinterFlags, DataTree,
DataValidationFlags,
};
static SEARCH_DIR: &str = "./assets/yang/";
fn main() -> std::io::Result<()> {
let ctx = Context::new(SEARCH_DIR, ContextFlags::NO_YANGLIBRARY)
.expect("Failed to create context");
for module_name in &["ietf-interfaces", "iana-if-type"] {
ctx.load_module(module_name, None)
.expect("Failed to load module");
}
let dtree = DataTree::parse_file(
&ctx,
File::open("./assets/data/interfaces.json")?,
DataFormat::JSON,
DataParserFlags::empty(),
DataValidationFlags::empty(),
)
.expect("Failed to parse data tree");
dtree
.print_file(
std::io::stdout(),
DataFormat::XML,
DataPrinterFlags::WD_ALL | DataPrinterFlags::WITH_SIBLINGS,
)
.expect("Failed to print data tree");
Ok(())
}
