In this tree, \fBmyproject\fR depends on \fBlog\fR with the \fBserde\fR feature. \fBlog\fR in
|
||
|
|
turn depends on \fBcfg\-if\fR with \[lq]default\[rq] features. When using \fB\-e features\fR it
|
||

can be helpful to use \fB\-i\fR flag to show how the features flow into a package.

.SS "Feature Unification"
|
||
|
|
This command shows a graph much closer to a feature\-unified graph Cargo will
|
||
|
|
build, rather than what you list in \fBCargo.toml\fR\&. For instance, if you specify
|
||
|
|
the same dependency in both \fB[dependencies]\fR and \fB[dev\-dependencies]\fR but with
|
||
|
|
different features on. This command may merge all features and show a \fB(*)\fR on
|
||
|
|
one of the dependency to indicate the duplicate.
|
||
|
|
.sp
|
||
|
|
As a result, for a mostly equivalent overview of what \fBcargo build\fR does,
|
||
|
|
\fBcargo tree \-e normal,build\fR is pretty close; for a mostly equivalent overview
|
||
|
|
of what \fBcargo test\fR does, \fBcargo tree\fR is pretty close. However, it doesn\[cq]t
|
||
|
|
guarantee the exact equivalence to what Cargo is going to build, since a
|
||
|
|
compilation is complex and depends on lots of different factors.

To read this graph, you can follow the chain for each feature from the root
|
||
|
|
to see why it is included. For example, the \[lq]full\[rq] feature is added by the
|
||
|
|
\fBrustversion\fR crate which is included from \fBmyproject\fR (with the default
|
||
|
|
features), and \fBmyproject\fR is the package selected on the command\-line. All
|
||
|
|
of the other \fBsyn\fR features are added by the \[lq]default\[rq] feature (\[lq]quote\[rq] is
|
||
|
|
added by \[lq]printing\[rq] and \[lq]proc\-macro\[rq], both of which are default features).
