.SH NAME
rustdoc \- generate documentation from Rust source code
.SH SYNOPSIS
.B rustdoc
[\fIOPTIONS\fR] \fIINPUT\fR

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

.SH OPTIONS

.TP
-r --input-format <val>
html or json (default: inferred)
.TP
-w --output-format <val>
html or json (default: html)
.TP
-o --output <val>
where to place the output (default: doc/ for html, doc.json for json)
.TP
--passes <val>
space-separated list of passes to run (default: '')
.TP
--no-defaults
don't run the default passes
.TP
--plugins <val>
space-separated list of plugins to run (default: '')
.TP
--plugin-path <val>
directory to load plugins from (default: /tmp/rustdoc_ng/plugins)
.TP
-L --library-path <val>
directory to add to crate search path
.TP
-h, --help

.SH "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.

.SH "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.
