Struct spinoso_symbol::NoSuchCaseFoldingScheme

pub struct NoSuchCaseFoldingScheme { /* private fields */ }

Available on crate feature artichoke only.

Error type for returned when a folding scheme could not be resolved in a TryFrom implementation.

When this crate’s std feature is enabled, NoSuchCaseFoldingScheme implements std::error::Error.

Examples

assert_eq!(CaseFold::try_from(None::<&str>), Ok(CaseFold::Full));
assert_eq!(CaseFold::try_from(Some("ascii")), Ok(CaseFold::Ascii));
assert_eq!(CaseFold::try_from(Some("turkic")), Ok(CaseFold::Turkic));
assert_eq!(CaseFold::try_from(Some("lithuanian")), Ok(CaseFold::Lithuanian));
assert_eq!(CaseFold::try_from(Some("xxx")), Err(NoSuchCaseFoldingScheme::new()));

Implementations

impl NoSuchCaseFoldingScheme

pub const fn new() -> NoSuchCaseFoldingScheme

Construct a new NoSuchCaseFoldingScheme error.

Examples

const ERR: NoSuchCaseFoldingScheme = NoSuchCaseFoldingScheme::new();

Trait Implementations

impl Clone for NoSuchCaseFoldingScheme

fn clone(&self) -> NoSuchCaseFoldingScheme

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NoSuchCaseFoldingScheme

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

Formats the value using the given formatter.

impl Default for NoSuchCaseFoldingScheme

fn default() -> NoSuchCaseFoldingScheme

Returns the “default value” for a type.

impl Display for NoSuchCaseFoldingScheme

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

Formats the value using the given formatter.

impl Error for NoSuchCaseFoldingScheme

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl Hash for NoSuchCaseFoldingScheme

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

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 NoSuchCaseFoldingScheme

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<NoSuchCaseFoldingScheme> for NoSuchCaseFoldingScheme

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd<NoSuchCaseFoldingScheme> for NoSuchCaseFoldingScheme

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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