Struct Flags 

pub struct Flags {
    pub ignore_case: Option<bool>,
    pub multiline: bool,
    pub dotall: bool,
    pub verbose: bool,
    pub unicode: bool,
    pub global: bool,
}

Configuration flags that modify the behavior of the regular expression engine.

Fields

ignore_case: Option<bool>

Controls case sensitivity.

• None: Smartcase (case-insensitive if pattern is all lowercase, sensitive otherwise).
• Some(true): Case-insensitive (i flag).
• Some(false): Case-sensitive (c flag).

multiline: bool

If true, ^ and $ match line boundaries (\n) instead of just the start/end of the text (m flag).

dotall: bool

If true, . matches newlines (s flag).

verbose: bool

If true, whitespace and comments in the pattern are ignored (x flag).

unicode: bool

If true, enables Unicode support for character classes (u flag).

global: bool

If true, indicates that the regex should match all occurrences (g flag). Note: This flag is often handled by the caller (e.g., find_all vs find), but is preserved here for parsing.

impl Debug for Flags

fn fmt(&self, f: &mut Formatter<'_>) -> Result
