| 35 | .SH "DESCRIPTION" |
| 36 | .sp |
| 37 | This command will display a tree of dependencies to the terminal. An example |
| 38 | of a simple project that depends on the "rand" package: |
| 39 | .sp |
| 40 | .if n .RS 4 |
| 41 | .nf |

| 57 | .sp |
| 58 | Packages marked with \fB(*)\fP have been "de\-duplicated". The dependencies for the |
| 59 | package have already been shown elswhere in the graph, and so are not |
| 60 | repeated. Use the \fB\-\-no\-dedupe\fP option to repeat the duplicates. |
| 61 | .sp |
| 62 | The \fB\-e\fP flag can be used to select the dependency kinds to display. The |
| 63 | "features" kind changes the output to display the features enabled by |
| 64 | each dependency. For example, \fBcargo tree \-e features\fP: |
| 65 | .sp |
| 66 | .if n .RS 4 |
| 67 | .nf |
| 68 | myproject v0.1.0 (/myproject) |

| 77 | In this tree, \fBmyproject\fP depends on \fBlog\fP with the \fBserde\fP feature. \fBlog\fP in |
| 78 | turn depends on \fBcfg\-if\fP with "default" features. When using \fB\-e features\fP it |
| 79 | can be helpful to use \fB\-i\fP flag to show how the features flow into a package. |
| 80 | See the examples below for more detail. |

| 84 | \fB\-i\fP \fISPEC\fP, \fB\-\-invert\fP \fISPEC\fP |
| 85 | .RS 4 |
| 86 | Show the reverse dependencies for the given package. This flag will invert |
| 87 | the tree and display the packages that depend on the given package. |
| 88 | .sp |
| 89 | Note that in a workspace, by default it will only display the package\(cqs |
| 90 | reverse dependencies inside the tree of the workspace member in the current |
| 91 | directory. The \fB\-\-workspace\fP flag can be used to extend it so that it will |
| 92 | show the package\(cqs reverse dependencies across the entire workspace. The \fB\-p\fP |
| 93 | flag can be used to display the package\(cqs reverse dependencies only with the |
| 94 | subtree of the package given to \fB\-p\fP. |
| 95 | .RE |
| 96 | .sp |
| 97 | \fB\-\-no\-dedupe\fP |
| 98 | .RS 4 |
| 99 | Do not de\-duplicate repeated dependencies. Usually, when a package has |
| 100 | already displayed its dependencies, further occurrences will not |
| 101 | re\-display its dependencies, and will include a \fB(*)\fP to indicate it has |
| 102 | already been shown. This flag will cause those duplicates to be repeated. |
| 103 | .RE |
| 104 | .sp |
| 105 | \fB\-d\fP, \fB\-\-duplicates\fP |
| 106 | .RS 4 |
| 107 | Show only dependencies which come in multiple versions (implies |
| 108 | \fB\-\-invert\fP). When used with the \fB\-p\fP flag, only shows duplicates within |
| 109 | the subtree of the given package. |
| 110 | .sp |
| 111 | It can be beneficial for build times and executable sizes to avoid building |
| 112 | that same package multiple times. This flag can help identify the offending |
| 113 | packages. You can then investigate if the package that depends on the |
| 114 | duplicate with the older version can be updated to the newer version so that |
| 115 | only one instance is built. |

| 596 | The \fB\-e features\fP flag is used to show features. The \fB\-i\fP flag is used to |
| 597 | invert the graph so that it displays the packages that depend on \fBsyn\fP. An |

| 626 | To read this graph, you can follow the chain for each feature from the root to |
| 627 | see why it is included. For example, the "full" feature is added by the |
| 628 | \fBrustversion\fP crate which is included from \fBmyproject\fP (with the default |
| 629 | features), and \fBmyproject\fP is the package selected on the command\-line. All |
| 630 | of the other \fBsyn\fP features are added by the "default" feature ("quote" is |
| 631 | added by "printing" and "proc\-macro", both of which are default features). |
| 632 | .sp |
| 633 | If you\(cqre having difficulty cross\-referencing the de\-duplicated \fB(*)\fP entries, |
| 634 | try with the \fB\-\-no\-dedupe\fP flag to get the full output. |
