Expand description

Generic trait for parsing types from various sources using GAT

This trait provides a unified interface for constructing types from different data sources (JSON values, XML elements, etc.) using Generic Associated Types (GAT) for flexible lifetime handling.

§Examples

use feedparser_rs::types::generics::ParseFrom;
use feedparser_rs::types::Person;
use serde_json::json;

let json = json!({"name": "John Doe", "url": "https://example.com"});
let person = Person::parse_from(&json);
assert!(person.is_some());
assert_eq!(person.unwrap().name.as_deref(), Some("John Doe"));

Required Methods§

Source

fn parse_from(source: Source) -> Option<Self>

Parse from the given source

§Arguments
  • source - The source data to parse from
§Returns
  • Some(Self) - Successfully parsed instance
  • None - Failed to parse (missing required fields, wrong type, etc.)

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
