Function extract_delimited_frontmatter

pub fn extract_delimited_frontmatter<'a>(
    content: &'a str,
    start_delim: &str,
    end_delim: &str,
) -> Option<&'a str>

Extracts frontmatter enclosed by the given start and end delimiters.

This function checks for frontmatter enclosed by delimiters like --- for YAML or +++ for TOML. It returns the extracted frontmatter if the delimiters are found.

Arguments

• content - The full content string containing frontmatter.
• start_delim - The starting delimiter (e.g., ---\n for YAML).
• end_delim - The ending delimiter (e.g., \n---\n for YAML).

Returns

An Option containing the extracted frontmatter as a string slice. Returns None if the delimiters are not found.

Example

use frontmatter_gen::extractor::extract_delimited_frontmatter;
let content = "---\ntitle: Example\n---\nContent";
let frontmatter = extract_delimited_frontmatter(content, "---\n", "\n---\n").unwrap();
assert_eq!(frontmatter, "title: Example");
