}
Expand description
Origin of the argument’s value
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
DefaultValue
Value came Arg::default_value
EnvVariable
Value came Arg::env
CommandLine
Value was passed in on the command-line
