Variants§
Opt
An option that takes a value, and cannot appear more than once (e.g. --out-dir
).
Corresponds to getopts::Options::optopt
.
Multi
An option that takes a value, and can appear multiple times (e.g. --emit
).
Corresponds to getopts::Options::optmulti
.
Flag
An option that does not take a value, and cannot appear more than once (e.g. --help
).
Corresponds to getopts::Options::optflag
.
The hint
string must be empty.
FlagMulti
An option that does not take a value, and can appear multiple times (e.g. -O
).
Corresponds to getopts::Options::optflagmulti
.
The hint
string must be empty.

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
