Library to serialize and deserialize [Syn] syntax trees.
Add this to your Cargo.toml:
toml
[dependencies]
syn-serde = "0.2"
Compiler support: requires rustc 1.56+
toml
[dependencies]
syn-serde = { version = "0.2", features = ["json"] }
syn = { version = "1", features = ["full"] }
```rust use syn_serde::json;
let synfile: syn::File = syn::parsequote! { fn main() { println!("Hello, world!"); } };
println!("{}", json::tostringpretty(&syn_file)); ```
This prints the following JSON:
json
{
"items": [
{
"fn": {
"ident": "main",
"inputs": [],
"output": null,
"stmts": [
{
"semi": {
"macro": {
"path": {
"segments": [
{
"ident": "println"
}
]
},
"delimiter": "paren",
"tokens": [
{
"lit": "\"Hello, world!\""
}
]
}
}
}
]
}
}
]
}
The [rust2json] example parse a Rust source file into a syn_serde::File
and print out a JSON representation of the syntax tree.
The [json2rust] example parse a JSON file into a syn_serde::File and
print out a Rust syntax tree.
json — Provides functions for JSON <-> Rust serializing and
deserializing.syn-serde is a fork of [Syn], and syn-serde provides a set of data structures similar but not identical to [Syn]. All data structures provided by syn-serde can be converted to the data structures of [Syn] and [proc-macro2].
The data structures of syn-serde 0.2 is compatible with the data structures of [Syn] 1.0.
