pub trait Syn: Sized + Sealed {

// Required methods
fn to_adapter(&self) -> Self::Adapter;
fn from_adapter(adapter: &Self::Adapter) -> Self;
}Expand description
A trait for the data structures of Syn and proc-macro2.
Required Associated Types§
type Adapter: Serialize + for<'de> Deserialize<'de>
Required Methods§
Sourcefn to_adapter(&self) -> Self::Adapter
fn to_adapter(&self) -> Self::Adapter
Converts a Syn type into an adapter.
§Examples
use syn_serde::Syn;
let syn_file: syn::File = syn::parse_quote! {
fn main() {
println!("Hello, world!");
}
};
let serializable_file = syn_file.to_adapter();
println!("{}", serde_json::to_string_pretty(&serializable_file).unwrap());Sourcefn from_adapter(adapter: &Self::Adapter) -> Self
fn from_adapter(adapter: &Self::Adapter) -> Self
Converts an adapter into a Syn type.
§Examples
use syn_serde::Syn;
// `struct Unit;`
let json = r#"{
"struct": {
"ident": "Unit",
"fields": "unit"
}
}"#;
let serializable_file: <syn::File as Syn>::Adapter = serde_json::from_str(json)?;
let syn_file = syn::File::from_adapter(&serializable_file);Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
