- html or json (default: inferred)
- -w, --output-format FORMAT
- html or json (default: html)
- -o, --output OUTPUT

- --passes LIST
- space-separated list of passes to run (default: '')
- --no-defaults
- don't run the default passes
- --plugins LIST
- space-separated list of plugins to run (default: '')
- --plugin-path DIR
- directory to load plugins from (default: /tmp/rustdoc_ng/plugins)
- --target TRIPLE
- target triple to document
- --crate-name NAME
- specify the name of this crate
- -L, --library-path DIR
- directory to add to crate search path

- --extern VAL
- pass an --extern to rustc
- --test
- run code examples as tests
- --test-args ARGS
- pass arguments to the test runner
- --html-in-header FILE
- file to add to <head>

- -h, --help
- Print help
- -V, --version
-
Print rustdoc's version
OUTPUT FORMATS
The rustdoc tool can generate output in either an HTML or JSON format.
If using an HTML format, then the specified output destination will be the root directory of an HTML structure for all the documentation. Pages will be placed into this directory, and source files will also possibly be rendered into it as well.
If using a JSON format, then the specified output destination will have the rustdoc output serialized as JSON into it. This output format exists to pre-compile documentation for crates, and for usage in non-rustdoc tools. The JSON output is the following hash:
{
"schema": VERSION,
"crate": ...,
"plugins": ...,
}
The schema version indicates what the structure of crate/plugins will look like. Within a schema version the structure will remain the same. The crate field will contain all relevant documentation for the source being documented, and the plugins field will contain the output of the plugins run over the crate.
EXAMPLES
To generate documentation for the source in the current directory:
$ rustdoc hello.rs
List all available passes that rustdoc has, along with default passes:
$ rustdoc --passes list
To precompile the documentation for a crate, and then use it to render html at
a later date:
$ rustdoc -w json hello.rs
$ rustdoc doc.json
The generated HTML can be viewed with any standard web browser.
