Enum Encoding

#[repr(u32)]
pub enum Encoding {
    Utf8 = 1,
    Latin1 = 2,
}

Encoding of text inputs.

When Self::Utf8 is selected (the default), re2 will happily accept str patterns and inputs:

 use re2::{*, options::*};

 let r: RE2 = "asdf".parse()?;
 assert_eq!(Encoding::Utf8, r.options().encoding);
 assert!(r.full_match("asdf"));

However, re2 will also accept Latin-1 encoded text. Each string method has a *_view-suffixed version which accepts a StringView, which can represent a slice of arbitrary bytes:

 use re2::{*, options::*};

 let o: Options = CannedOptions::Latin1.into();
 let r = RE2::compile("asdf", o)?;
 assert_eq!(Encoding::Latin1, r.options().encoding);
 assert!(r.full_match("asdf"));

Variants

Utf8 = 1

Assume UTF-8 encoded text.

Latin1 = 2

Assume Latin-1 encoded text.

Trait Implementations

impl Clone for Encoding

fn clone(&self) -> Encoding

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Encoding

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

Formats the value using the given formatter.

impl Default for Encoding

fn default() -> Encoding

Returns the “default value” for a type.

impl Display for Encoding

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

Formats the value using the given formatter.

impl From<Encoding> for u32

fn from(enum_value: Encoding) -> Self

Converts to this type from the input type.

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: &Encoding) -> 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.

impl TryFrom<u32> for Encoding

type Error = TryFromPrimitiveError<Encoding>

The type returned in the event of a conversion error.

fn try_from(number: u32) -> Result<Self, TryFromPrimitiveError<Self>>

Performs the conversion.

impl TryFromPrimitive for Encoding

const NAME: &'static str = "Encoding"

type Primitive = u32

fn try_from_primitive( number: Self::Primitive, ) -> Result<Self, TryFromPrimitiveError<Self>>

impl Copy for Encoding

impl Eq for Encoding

impl StructuralPartialEq for Encoding
