Struct MultiCrateParser 

pub struct MultiCrateParser;

Parser for multiple rustdoc JSON files in a directory.

Discovers JSON files and parses each one, extracting the crate name from the root module item.

Example

let crates = MultiCrateParser::parse_directory(Path::new("target/doc"))?;
println!("Found {} crates", crates.len());

Implementations

impl MultiCrateParser

pub fn parse_directory(dir: &Path) -> Result<CrateCollection, Error>

Parse all rustdoc JSON files in a directory.

Scans the top level of the directory for *.json files and attempts to parse each one as rustdoc JSON. Files that aren’t valid rustdoc JSON (e.g., search indices) are silently skipped.

Arguments

• dir - Path to directory containing JSON files

Returns

A CrateCollection containing all successfully parsed crates.

Errors

• Error::InvalidDirectory if the path is invalid
• Error::NoJsonFiles if no valid JSON files found
• Error::DuplicateCrate if multiple files define the same crate
• Error::NoCrateName if a JSON file has no root module
