[−][src]Struct regex_syntax::ast::Flags

pub struct Flags {
    pub span: Span,
    pub items: Vec<FlagsItem>,
}
[−]

A group of flags.

This corresponds only to the sequence of flags themselves, e.g., is-u.

Fields

span: Span
[−]

The span of this group of flags.

items: Vec<FlagsItem>
[−]

A sequence of flag items. Each item is either a flag or a negation operator.

Methods

impl Flags[src][−]

pub fn add_item(&mut self, item: FlagsItem) -> Option<usize>[src][−]

Add the given item to this sequence of flags.

If the item was added successfully, then None is returned. If the given item is a duplicate, then Some(i) is returned, where items[i].kind == item.kind.

pub fn flag_state(&self, flag: Flag) -> Option<bool>[src][−]

Returns the state of the given flag in this set.

If the given flag is in the set but is negated, then Some(false) is returned.

If the given flag is in the set and is not negated, then Some(true) is returned.

Otherwise, None is returned.
