Struct Flags

pub struct Flags { /* private fields */ }

A checked interface for setting regular expression flags.

Note that the From<&str> impl is just a shortcut for new_unchecked.

Implementations

impl Flags

pub fn new(source: &str) -> Option<Self>

Takes a source flags string using the same format as the JavaScript RegExp constructor, but returns None if invalid flags, or invalid combinations of flags, are used.

pub fn new_unchecked(source: &str) -> Self

Same as new, but doesn’t care about invalid, duplicate, or bad combinations of flags. Will instead ignore invalid flags, and cause the RegExp constructors to report syntax errors from their JavaScript calls if invalid combinations are used.

pub fn inspect(&self) -> &FlagSets

The inner FlagSets
