Struct CasefoldStr 

pub struct CasefoldStr(/* private fields */);

A borrowed slice of a casefolded string.

It is designed to be the borrowed counterpart to CasefoldString, mirroring the relationship between str and String.

We wrap str instead of a struct like CasefoldStr<'a>(&'a str) so that CasefoldString can implement Deref<Target = CasefoldStr>. This allows CasefoldString to coerce to &CasefoldStr automatically, and enables zero-allocation map lookups via Borrow<CasefoldStr>.

Implementations

impl CasefoldStr

pub fn new(s: &str) -> &Self

pub fn as_str(&self) -> &str

pub fn casefold_normalized_chars(&self) -> impl Iterator<Item = char> + '_

Trait Implementations

impl Borrow<CasefoldStr> for CasefoldString

fn borrow(&self) -> &CasefoldStr

Immutably borrows from an owned value.

impl Debug for CasefoldStr

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

Formats the value using the given formatter.

impl Display for CasefoldStr

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

Formats the value using the given formatter.

impl<'a> From<&'a str> for &'a CasefoldStr

fn from(item: &'a str) -> Self

Converts to this type from the input type.

impl Hash for CasefoldStr

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

Feeds this value into the given Hasher.

impl Ord for CasefoldStr

fn cmp(&self, rhs: &Self) -> Ordering

This method returns an Ordering between self and other.

impl PartialEq for CasefoldStr

fn eq(&self, rhs: &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 CasefoldStr

fn partial_cmp(&self, rhs: &Self) -> 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 ToOwned for CasefoldStr

type Owned = CasefoldString

The resulting type after obtaining ownership.

fn to_owned(&self) -> Self::Owned

Creates owned data from borrowed data, usually by cloning.

fn clone_into(&self, target: &mut Self::Owned)

Uses borrowed data to replace owned data, usually by cloning.
