Enum CodepointsError

pub enum CodepointsError {
    InvalidUtf8Codepoint,
}

Error returned when failing to construct a Codepoints iterator/

This error is returned from String::codepoints. See its documentation for more detail.

This error corresponds to the Ruby ArgumentError Exception class.

When the std feature of spinoso-string is enabled, this struct implements std::error::Error.

Variants

InvalidUtf8Codepoint

Error returned when calling String::codepoints on a String with UTF-8 encoding which is not a valid UTF-8 byte string.

Implementations

impl CodepointsError

pub const EXCEPTION_TYPE: &'static str = "ArgumentError"

pub const fn invalid_utf8_codepoint() -> Self

Create a new invalid UTF-8 codepoint CodepointsError.

Examples

use spinoso_string::CodepointsError;

const ERR: CodepointsError = CodepointsError::invalid_utf8_codepoint();
assert_eq!(ERR.message(), "invalid byte sequence in UTF-8");

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

Retrieve the exception message associated with this center error.

Examples

let err = CodepointsError::invalid_utf8_codepoint();
assert_eq!(err.message(), "invalid byte sequence in UTF-8");

Trait Implementations

impl Clone for CodepointsError

fn clone(&self) -> CodepointsError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CodepointsError

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

Formats the value using the given formatter.

impl Display for CodepointsError

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

Formats the value using the given formatter.

impl Error for CodepointsError

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

Returns 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, request: &mut Request<'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 CodepointsError

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 CodepointsError

fn cmp(&self, other: &CodepointsError) -> 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 CodepointsError

fn eq(&self, other: &CodepointsError) -> 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 CodepointsError

fn partial_cmp(&self, other: &CodepointsError) -> 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.
