Function parse_md_docblock

pub fn parse_md_docblock(md: &str) -> Result<DocBlock, ParseError>

Parse documentation and extract data

Parameters

• md: Markdown string, needs to be parseable by pulldown-cmark

Returns

A Result, which is either

• Ok(DocBlock): A type that contains all extracted information (including all unknown sections as Custom sections).
• Err(ParseError): The first encountered error while parsing the documentation string.

Examples

Please excuse the weird way the input is formatted in this example. Embedding Markdown strings in Rust code examples, which are just code blocks in Markdown documentation strings inside a Rust program is hard! (Rustdoc treads # at the beginning of code example line as a sign it should omit the line from output. Sadly, this means I can’t write Markdown headlines as usual.)

assert_eq!(parse_md_docblock(
    "Lorem ipsum\n\nDolor sit amet.\n\n# Parameters\n\n- `param1`: Foo\n- `param2`: Bar\n"
).unwrap(),
    DocBlock {
        teaser: "Lorem ipsum".into(),
        description: Some("Dolor sit amet.".into()),
        sections: vec![
            DocSection::Parameters(vec![
                ("param1".into(), "Foo".into()),
                ("param2".into(), "Bar".into())
            ])
        ]
    }
