Enum Encoding

pub enum Encoding {
    Fixed,
    No,
    None,
}

The encoding of a Regexp literal.

Regexps are assumed to use the source encoding but literals may override the encoding with a Regexp modifier.

See Regexp encoding.

Implementations

impl Encoding

pub const fn new() -> Self

Construct a new None encoding.

pub const fn flags(self) -> Flags

Convert an Encoding to its bit flag representation.

Alias for the corresponding Into<Flags> implementation.

pub const fn into_bits(self) -> u8

Convert an Encoding to its bit representation.

Alias for the corresponding Into<u8> implementation.

pub const fn as_modifier_str(self) -> &'static str

Serialize the encoding flags to a string suitable for a Regexp display or debug implementation.

See also Regexp#inspect.

Trait Implementations

impl Clone for Encoding

fn clone(&self) -> Encoding

Returns a copy of the value.

Formats the value using the given formatter.

impl Default for Encoding

fn default() -> Self

Returns the “default value” for a type.

impl Display for Encoding

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

Formats the value using the given formatter.

impl From<&Encoding> for Flags

fn from(encoding: &Encoding) -> Self

Convert an Encoding to its bit flag representation.

impl From<&Encoding> for i64

fn from(encoding: &Encoding) -> Self

Convert an Encoding to its widened bit representation.

impl From<&Encoding> for u8

fn from(encoding: &Encoding) -> Self

Convert an Encoding to its bit representation.

impl From<Encoding> for Flags

fn from(encoding: Encoding) -> Self

impl From<Encoding> for i64

fn from(encoding: Encoding) -> Self

Convert an Encoding to its widened bit representation.

impl From<Encoding> for u8

fn from(encoding: Encoding) -> Self

impl Hash for Encoding

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Encoding

fn cmp(&self, other: &Encoding) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Encoding

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Encoding

fn partial_cmp(&self, other: &Encoding) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
