Enum nu_errors::ArgumentError [−][src]
pub enum ArgumentError { MissingMandatoryFlag(String), MissingMandatoryPositional(String), MissingValueForName(String), UnexpectedArgument(Spanned<String>), UnexpectedFlag(Spanned<String>), InvalidExternalWord, }
Expand description
ArgumentError describes various ways that the parser could fail because of unexpected arguments. Nu commands are like a combination of functions and macros, and these errors correspond to problems that could be identified during expansion based on the syntactic signature of a command.
Variants
MissingMandatoryFlag(String)
Expand description
The command specified a mandatory flag, but it was missing.
MissingMandatoryPositional(String)
Expand description
The command specified a mandatory positional argument, but it was missing.
MissingValueForName(String)
Expand description
A flag was found, and it should have been followed by a value, but no value was found
Expand description
An argument was found, but the command does not recognize it
Expand description
An flag was found, but the command does not recognize it
Expand description
A sequence of characters was found that was not syntactically valid (but would have been valid if the command was an external command)
