Enum TextError

#[non_exhaustive]
pub enum TextError {
    ElementNotFound,
    InvalidChar(char),
    InvalidUtf8 {
        valid_up_to: Option<usize>,
        error_len: Option<usize>,
    },
    MismatchedCapacity(Mismatch<Interval<usize>, usize>),
}

Available on crate feature error and text·· only.

🚩+ A text-related composite error.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ElementNotFound

The requested element has not been found.

InvalidChar(char)

An invalid given character was found.

InvalidUtf8

Invalid Utf-8 found while interpreting a byte sequence.

This is basically a replication of core::str::Utf8Error.

Fields

valid_up_to: Option<usize>

The index in the given string up to which valid UTF-8 was verified.

error_len: Option<usize>

The length of the error in bytes, if known.

MismatchedCapacity(Mismatch<Interval<usize>, usize>)

The given capacity did not match the required constraints.

Trait Implementations

impl Clone for TextError

fn clone(&self) -> TextError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TextError

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

Formats the value using the given formatter.

impl Display for TextError

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

Formats the value using the given formatter.

impl Error for TextError

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 ExtError for TextError

type Kind = ()

Represents the specific kind of error, if applicable.

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

Checks if two errors are equivalent based on their kind or other criteria.

fn error_kind(&self) -> Self::Kind

Returns the kind of the error, if applicable.

impl From<ElementNotFound> for TextError

fn from(_f: ElementNotFound) -> TextError

Converts to this type from the input type.

impl From<InvalidChar> for TextError

fn from(_f: InvalidChar) -> TextError

Converts to this type from the input type.

impl From<InvalidText> for TextError

fn from(f: InvalidText) -> TextError

Converts to this type from the input type.

impl From<InvalidUtf8> for TextError

fn from(_f: InvalidUtf8) -> TextError

Converts to this type from the input type.

impl From<MismatchedCapacity> for TextError

fn from(_f: MismatchedCapacity) -> TextError

Converts to this type from the input type.

impl Hash for TextError

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 PartialEq for TextError

fn eq(&self, other: &TextError) -> 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.
