oci-spec is a library for Serialize/Deserialize oci-runtime-spec and oci-image-spec config.
Use load of Spec to deserialize oci-runtime-spec config.
If it is a required item in oci-runtime-spec but there is no value in JSON, an error will occur. Also, if there is no JSON value in the optional item in oci-runtime-spec, None will be set.
For example, ociVersion is a required item in oci-runtime-spec, but if ociVersion does not exist in JSON, an error occurs.
Although root is an object type and internally has a required path, no error occurs even if there is no value in JSON.
However, if root has a value in JSON and the value of the required item held internally is not in JSON, an error occurs.
``` extern crate oci_spec;
use oci_spec::runtime::Spec;
fn main() { // Deserialize oci runtime specification config. let spec = match Spec::load("config.json") { Ok(s) => s, Err(e) => panic!("{}", e), } println!("oci-runtime-spec version is {}", spec.version); } ```
Use save of Spec to serialize oci runtime spec config.
If the type is Option and the value is None, it is not serialized.
``` extern crate oci_spec;
use oci_spec::runtime::Spec;
fn main() { // Deserialize oci runtime specification config. let spec = match Spec::load("config.json") { Ok(s) => s, Err(e) => panic!("{}", e), } println!("oci-runtime-spec version is {}", spec.version);
// Serialize oci runtime specification config.
match Spec::save(&spec, "config.json") {
Ok(_) => {},
Err(e) => panic!("{}", e),
}
} ```
