//! JSON Feed is a syndication format similar to ATOM and RSS, using JSON //! instead of XML //! //! This crate can serialize and deserialize between JSON Feed strings //! and Rust data structures. It also allows for programmatically building //! a JSON Feed //! //! Example: //! //! ```rust //! extern crate jsonfeed; //! //! use jsonfeed::{Feed, Item}; //! //! fn run() -> Result<(), jsonfeed::Error> { //! let j = r#"{ //! "title": "my feed", //! "version": "https://jsonfeed.org/version/1", //! "items": [] //! }"#; //! let feed: Feed = jsonfeed::from_str(j).unwrap(); //! //! let new_feed = Feed::builder() //! .title("some other feed") //! .item(Item::builder() //! .title("some item title") //! .content_html("<p>Hello, World</p>") //! .build()?) //! .item(Item::builder() //! .title("some other item title") //! .content_text("Hello, World!") //! .build()?) //! .build(); //! println!("{}", new_feed.to_string().unwrap()); //! Ok(()) //! } //! fn main() { //! let _ = run(); //! } //! ``` extern crate serde; #[macro_use] extern crate error_chain; #[macro_use] extern crate serde_derive; extern crate serde_json; mod errors; mod item; mod feed; mod builder; pub use errors::*; pub use item::*; pub use feed::{Feed, Author, Content, Attachment}; use std::io::Write; /// Attempts to convert a string slice to a Feed object /// /// Example /// /// ```rust /// # extern crate jsonfeed; /// # use jsonfeed::Feed; /// # use std::default::Default; /// # fn main() { /// let json = r#"{"version": "https://jsonfeed.org/version/1", "title": "", "items": []}"#; /// let feed: Feed = jsonfeed::from_str(&json).unwrap(); /// /// assert_eq!(feed, Feed::default()); /// # } /// ``` pub fn from_str(s: &str) -> Result<Feed> { Ok(serde_json::from_str(s)?) } /// Deserialize a Feed object from an IO stream of JSON pub fn from_reader<R: ::std::io::Read>(r: R) -> Result<Feed> { Ok(serde_json::from_reader(r)?) } /// Deserialize a Feed object from bytes of JSON text pub fn from_slice<'a>(v: &'a [u8]) -> Result<Feed> { Ok(serde_json::from_slice(v)?) } /// Convert a serde_json::Value type to a Feed object pub fn from_value(value: serde_json::Value) -> Result<Feed> { Ok(serde_json::from_value(value)?) } /// Serialize a Feed to a JSON Feed string pub fn to_string(value: &Feed) -> Result<String> { Ok(serde_json::to_string(value)?) } /// Pretty-print a Feed to a JSON Feed string pub fn to_string_pretty(value: &Feed) -> Result<String> { Ok(serde_json::to_string_pretty(value)?) } /// Convert a Feed to a serde_json::Value pub fn to_value(value: Feed) -> Result<serde_json::Value> { Ok(serde_json::to_value(value)?) } /// Convert a Feed to a vector of bytes of JSON pub fn to_vec(value: &Feed) -> Result<Vec<u8>> { Ok(serde_json::to_vec(value)?) } /// Convert a Feed to a vector of bytes of pretty-printed JSON pub fn to_vec_pretty(value: &Feed) -> Result<Vec<u8>> { Ok(serde_json::to_vec_pretty(value)?) } /// Serialize a Feed to JSON and output to an IO stream pub fn to_writer<W>(writer: W, value: &Feed) -> Result<()> where W: Write { Ok(serde_json::to_writer(writer, value)?) } /// Serialize a Feed to pretty-printed JSON and output to an IO stream pub fn to_writer_pretty<W>(writer: W, value: &Feed) -> Result<()> where W: Write { Ok(serde_json::to_writer_pretty(writer, value)?) }
