.SH "DESCRIPTION"
|
|
This command will run a credential provider to save a token so that commands
|
|
that require authentication, such as \fBcargo\-publish\fR(1), will be
|
|
automatically authenticated.
|
|
.sp
|
|
All the arguments following the two dashes (\fB\-\-\fR) are passed to the credential provider.
|
|
.sp
|
|
For the default \fBcargo:token\fR credential provider, the token is saved
|
|
in \fB$CARGO_HOME/credentials.toml\fR\&. \fBCARGO_HOME\fR defaults to \fB\&.cargo\fR
|
|
in your home directory.
|
|
.sp
|
|
If a registry has a credential\-provider specified, it will be used. Otherwise,
|
|
the providers from the config value \fBregistry.global\-credential\-providers\fR will
|
|
be attempted, starting from the end of the list.
|
|
.sp
|
|
If the \fItoken\fR argument is not specified, it will be read from stdin.
|
|
.sp
|
|
The API token for crates.io may be retrieved from <https://crates.io/me>\&.
|
|
.sp
|
|
Take care to keep the token secret, it should not be shared with anyone else.

.RS 4
|
|
If Cargo has been installed with rustup, and the first argument to \fBcargo\fR
|
|
begins with \fB+\fR, it will be interpreted as a rustup toolchain name (such
|
|
as \fB+stable\fR or \fB+nightly\fR).
|
|
See the \fIrustup documentation\fR <https://rust\-lang.github.io/rustup/overrides.html>

or provided as a path to an extra configuration file. This flag may be specified multiple times.

\fB\-C\fR \fIPATH\fR

Changes the current working directory before executing any specified operations. This affects
|
|
things like where cargo looks by default for the project manifest (\fBCargo.toml\fR), as well as
|
|
the directories searched for discovering \fB\&.cargo/config.toml\fR, for example. This option must
|
|
appear before the command name, for example \fBcargo \-C path/to/my\-project build\fR\&.
|
|
.sp
|
|
This option is only available on the \fInightly
|
|
channel\fR <https://doc.rust\-lang.org/book/appendix\-07\-nightly\-rust.html> and

|
requires the \fB\-Z unstable\-options\fR flag to enable (see
