Struct avocado::literal::RegexOpts

pub struct RegexOpts { /* fields omitted */ }

Options for matching text against a regular expression. Useful with the $regex operator. E.g.:

let query = doc!{
    "name": {
        "$regex": "^Foo",
        "$options": RegexOpts::LINE_ANCHOR | RegexOpts::IGNORE_CASE,
    },
    "address": {
        "$regex": ".* street$",
        "$options": RegexOpts::default(),
    },
};
assert_eq!(query, doc!{
    "name": {
        "$regex": "^Foo",
        "$options": "im",
    },
    "address": {
        "$regex": ".* street$",
        "$options": "",
    },
});

Methods

impl RegexOpts

pub const IGNORE_CASE: RegexOpts

Case insensitive matching.

"extended" syntax, allows embedded whitespace and #-comments

pub const DOT_NEWLINE: RegexOpts

The . character matches newlines too.

pub fn empty() -> RegexOpts

Returns an empty set of flags.

pub fn all() -> RegexOpts

Returns the set containing all flags.

pub fn bits(&self) -> u8

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u8) -> Option<RegexOpts>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub fn from_bits_truncate(bits: u8) -> RegexOpts

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub fn intersects(&self, other: RegexOpts) -> bool

Returns true if there are flags common to both self and other.

pub fn contains(&self, other: RegexOpts) -> bool

Returns true all of the flags in other are contained within self.

pub fn insert(&mut self, other: RegexOpts)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: RegexOpts)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: RegexOpts)

Toggles the specified flags in-place.

pub fn set(&mut self, other: RegexOpts, value: bool)
