Enum RunResult 

pub enum RunResult {
    Handled(String),
    Binary(Vec<u8>, String),
    Silent,
    NoMatch(ArgMatches),
}

Result of running the CLI dispatcher.

After processing arguments, the dispatcher either handles a command or falls through for manual handling.

Variants

Handled(String)

A handler processed the command; contains the rendered output

Binary(Vec<u8>, String)

A handler produced binary output (bytes, suggested filename)

Silent

Silent output (handler completed but produced no output)

NoMatch(ArgMatches)

No handler matched; contains the ArgMatches for manual handling

Implementations

impl RunResult

pub fn is_handled(&self) -> bool

Returns true if a handler processed the command (text output).

pub fn is_binary(&self) -> bool

Returns true if the result is binary output.

pub fn is_silent(&self) -> bool

Returns true if the result is silent.

pub fn output(&self) -> Option<&str>

Returns the output if handled, or None otherwise.

pub fn binary(&self) -> Option<(&[u8], &str)>

Returns the binary data and filename if binary, or None otherwise.

pub fn matches(&self) -> Option<&ArgMatches>

Returns the matches if unhandled, or None if handled.
