.SH "NAME"
cargo\-init \- Create a new Cargo package in an existing directory
.SH "SYNOPSIS"
.sp
\fBcargo init [\fIOPTIONS\fP] [\fIPATH\fP]\fP
.SH "DESCRIPTION"
.sp
This command will create a new Cargo manifest in the current directory. Give a
path as an argument to create in the given directory.
.sp
If there are typically\-named Rust source files already in the directory, those
will be used. If not, then a sample \fBsrc/main.rs\fP file will be created, or
\fBsrc/lib.rs\fP if \fB\-\-lib\fP is passed.
.sp
If the directory is not already in a VCS repository, then a new repository
is created (see \fB\-\-vcs\fP below).
.sp
The "authors" field in the manifest is determined from the environment or
configuration settings. A name is required and is determined from (first match
wins):

See \fBcargo\-new\fP(1) for a similar command which will create a new package in
a new directory.
.SH "OPTIONS"
.SS "Init Options"
.sp
\fB\-\-bin\fP
.RS 4
Create a package with a binary target (\fBsrc/main.rs\fP).
This is the default behavior.
.RE
.sp
\fB\-\-lib\fP
.RS 4
Create a package with a library target (\fBsrc/lib.rs\fP).
.RE
.sp
\fB\-\-edition\fP \fIEDITION\fP
.RS 4
Specify the Rust edition to use. Default is 2018.
Possible values: 2015, 2018
.RE

\fB\-\-name\fP \fINAME\fP
.RS 4
Set the package name. Defaults to the directory name.
.RE
.sp
\fB\-\-vcs\fP \fIVCS\fP
.RS 4
Initialize a new VCS repository for the given version control system (git,
hg, pijul, or fossil) or do not initialize any version control at all

.RE
.sp
\fB\-\-registry\fP \fIREGISTRY\fP

If not specified, the default registry defined by the \fBregistry.default\fP
config key is used. If the default registry is not set and \fB\-\-registry\fP is not
used, the \fBpublish\fP field will not be set which means that publishing will not
be restricted.
