Struct argh::EarlyExit

pub struct EarlyExit {
    pub output: String,
    pub status: Result<(), ()>,
}

Information to display to the user about why a FromArgs construction exited early.

This can occur due to either failed parsing or a flag like --help.

Fields

output: String

The output to display to the user of the commandline tool.

status: Result<(), ()>

Status of argument parsing.

Ok if the command was parsed successfully and the early exit is due to a flag like --help causing early exit with output.

Err if the arguments were not successfully parsed.

Trait Implementations

impl Clone for EarlyExit

fn clone(&self) -> EarlyExit

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EarlyExit

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<String> for EarlyExit

fn from(err_msg: String) -> Self

Converts to this type from the input type.

impl PartialEq<EarlyExit> for EarlyExit

fn eq(&self, other: &EarlyExit) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
