NAME

6       cargo-update - Update dependencies as recorded in the local lock file
7

SYNOPSIS

9       cargo update [options]
10

DESCRIPTION

12       This command will update dependencies in the Cargo.lock file to the
13       latest version. If the Cargo.lock file does not exist, it will be
14       created with the latest available versions.
15

OPTIONS

17   Update Options
18       -p spec..., --package spec...
19           Update only the specified packages. This flag may be specified
20           multiple times. See cargo-pkgid(1) for the SPEC format.
21
22           If packages are specified with the -p flag, then a conservative
23           update of the lockfile will be performed. This means that only the
24           dependency specified by SPEC will be updated. Its transitive
25           dependencies will be updated only if SPEC cannot be updated without
26           updating dependencies. All other dependencies will remain locked at
27           their currently recorded versions.
28
29           If -p is not specified, all dependencies are updated.
30
31       --aggressive
32           When used with -p, dependencies of spec are forced to update as
33           well. Cannot be used with --precise.
34
35       --precise precise
36           When used with -p, allows you to specify a specific version number
37           to set the package to. If the package comes from a git repository,
38           this can be a git revision (such as a SHA hash or tag).
39
40       -w, --workspace
41           Attempt to update only packages defined in the workspace. Other
42           packages are updated only if they don't already exist in the
43           lockfile. This option is useful for updating Cargo.lock after
44           you've changed version numbers in Cargo.toml.
45
46       --dry-run
47           Displays what would be updated, but doesn't actually write the
48           lockfile.
49
50   Display Options
51       -v, --verbose
52           Use verbose output. May be specified twice for "very verbose"
53           output which includes extra output such as dependency warnings and
54           build script output. May also be specified with the term.verbose
55           config value
56           <https://doc.rust-lang.org/cargo/reference/config.html>.
57
58       -q, --quiet
59           No output printed to stdout.
60
61       --color when
62           Control when colored output is used. Valid values:
63
64           ·  auto (default): Automatically detect if color support is
65               available on the terminal.
66
67           ·  always: Always display colors.
68
69           ·  never: Never display colors.
70
71           May also be specified with the term.color config value
72           <https://doc.rust-lang.org/cargo/reference/config.html>.
73
74   Manifest Options
75       --manifest-path path
76           Path to the Cargo.toml file. By default, Cargo searches for the
77           Cargo.toml file in the current directory or any parent directory.
78
79       --frozen, --locked
80           Either of these flags requires that the Cargo.lock file is
81           up-to-date. If the lock file is missing, or it needs to be updated,
82           Cargo will exit with an error. The --frozen flag also prevents
83           Cargo from attempting to access the network to determine if it is
84           out-of-date.
85
86           These may be used in environments where you want to assert that the
87           Cargo.lock file is up-to-date (such as a CI build) or want to avoid
88           network access.
89
90       --offline
91           Prevents Cargo from accessing the network for any reason. Without
92           this flag, Cargo will stop with an error if it needs to access the
93           network and the network is not available. With this flag, Cargo
94           will attempt to proceed without the network if possible.
95
96           Beware that this may result in different dependency resolution than
97           online mode. Cargo will restrict itself to crates that are
98           downloaded locally, even if there might be a newer version as
99           indicated in the local copy of the index. See the cargo-fetch(1)
100           command to download dependencies before going offline.
101
102           May also be specified with the net.offline config value
103           <https://doc.rust-lang.org/cargo/reference/config.html>.
104
105   Common Options
106       +toolchain
107           If Cargo has been installed with rustup, and the first argument to
108           cargo begins with +, it will be interpreted as a rustup toolchain
109           name (such as +stable or +nightly). See the rustup documentation
110           <https://rust-lang.github.io/rustup/overrides.html> for more
111           information about how toolchain overrides work.
112
113       -h, --help
114           Prints help information.
115
116       -Z flag
117           Unstable (nightly-only) flags to Cargo. Run cargo -Z help for
118           details.

ENVIRONMENT

121       See the reference
122       <https://doc.rust-lang.org/cargo/reference/environment-variables.html>

124

EXIT STATUS

126       ·  0: Cargo succeeded.
