Struct Flags 

pub struct Flags {
    pub i: bool,
    pub m: bool,
    pub s: bool,
    pub u: bool,
    pub x: bool,
    pub a: bool,
}

Set of semantic flags. Flags that do not change the language (ES g, y, d) are accepted by Flags::from_letters and reported as notes.

Fields

i: bool

i case-insensitive.

m: bool

m multiline.

s: bool

s dot matches newline.

u: bool

u Unicode.

x: bool

x extended / verbose.

a: bool

a ASCII-only classes.

Implementations

impl Flags

pub fn none() -> Self

No flags.

pub fn union(self, o: Flags) -> Flags

Union of two flag sets.

pub fn minus(self, o: Flags) -> Flags

self with the letters of o removed.

pub fn valid_letters(dialect: Dialect) -> &'static str

Flags valid for dialect, as shown in RX-P003.

pub fn from_letters( dialect: Dialect, letters: &str, ) -> Result<(Flags, Vec<String>), RexactError>

Parse option letters for a dialect. Returns the flags and notes about letters that were accepted but do not change the language.
