    next_is_unstable_option: bool,
    expanded: Vec<String>,

Implementations

impl Expander

fn arg(&mut self, arg: &str) -> Result<(), Error>

Handles the next argument. If the argument is an argfile, it is expanded inline.

fn push(&mut self, arg: String)

Adds a command line argument verbatim with no argfile expansion.

fn finish(self) -> Vec<String>

Consumes the Expander, returning the expanded arguments.

fn inspect_unstable_option(&mut self, option: &str)

Parses any relevant unstable flags specified on the command line.

fn read_file(path: &str) -> Result<String, Error>

Reads the contents of a file as UTF-8.

Trait Implementations

impl Default for Expander

Returns the “default value” for a type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
