Struct ParseOptions 

pub struct ParseOptions { /* private fields */ }

Options for configuring command-line parsing.

For backwards compatibility with 2.1, you can convert a bool into this type. true will be the default, and false will be no_strict_escapes.

Implementations

impl ParseOptions

pub const fn new() -> ParseOptions

Create a new ParseOptions starting at the defaults.

Equivalent to ParseOptions::default(), except that it’s a const fn so you can put it into a const variable if you like.

pub const fn no_strict_escapes(self) -> Self

The default is for bad escape sequences to result in a ParseError. If no_strict_escapes() is used, then bad escape sequences will result in ‘�’ instead.

pub const fn comment_char(self, comment_char: Option<char>) -> Self

The default is for comments to be delimited by a # character. You can specify another comment character, or disable comment delimiting, using comment_char().

pub const fn allow_comments_within_elements(self) -> Self

The default is that comments will only count if they are preceded by whitespace. Thus, by default, foo bar#baz # bang will parse as ["foo", "bar#baz"]. This matches the behavior of the Bourne shell. You can override this behavior by calling allow_comments_within_elements(), which would make that line parse as ["foo", "bar"] instead.
