Struct regress::Flags

pub struct Flags {
    pub icase: bool,
    pub multiline: bool,
    pub dot_all: bool,
    pub no_opt: bool,
    pub unicode: bool,
    pub unicode_sets: bool,
}

Flags used to control regex parsing. The default flags are case-sensitive, not-multiline, and optimizing.

Fields

icase: bool

If set, make the regex case-insensitive. Equivalent to the ‘i’ flag in JavaScript.

multiline: bool

If set, ^ and $ match at line separators, not just the input boundaries. Equivalent to the ‘m’ flag in JavaScript.

dot_all: bool

If set, . matches at line separators as well as any other character. Equivalent to the ‘m’ flag in JavaScript.

no_opt: bool

If set, disable regex IR passes.

unicode: bool

If set, the regex is interpreted as a Unicode regex. Equivalent to the ‘u’ flag in JavaScript.

unicode_sets: bool

If set, the regex is interpreted as a UnicodeSets regex. Equivalent to the ‘v’ flag in JavaScript.

Implementations

impl Flags

pub fn new<T: Iterator<Item = u32>>(chars: T) -> Self

Construct a Flags from a Unicode codepoints iterator, using JavaScript field names. ‘i’ means to ignore case, ‘m’ means multiline, ‘u’ means unicode. Note the ‘g’ flag implies a stateful regex and is not supported. Other flags are not implemented and are ignored.
