RUSTDOC(1)

NAME
rustdoc - generate documentation from Rust source code

SYNOPSIS
rustdoc [OPTIONS] INPUT

DESCRIPTION
This tool generates API reference documentation by extracting comments from source code written in the Rust language, available at <https://www.rust-lang.org>. It accepts several input formats and provides several output formats for the generated documentation.

OPTIONS

-r, --input-format FORMAT
    html or json (default: inferred)

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

-o, --output OUTPUT
    where to place the output (default: doc/ for html, doc.json for json)

--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

--cfg SPEC
    pass a --cfg to rustc

--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>

--html-before-content FILE
    file to add in <body>, before content

--html-after-content FILE
    file to add in <body>, after content

--markdown-css FILE
    CSS files to include via <link> in a rendered Markdown file

--markdown-playground-url URL
    URL to send code snippets to

--markdown-no-toc
    don't include table of contents

-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.
