Enum TextError 

#[non_exhaustive]
pub enum TextError {
    ElementNotFound,
    InvalidChar(char),
    InvalidUtf8 {
        valid_up_to: usize,
        error_len: Option<usize>,
    },
    MismatchedCapacity {
        bound: Boundary1d,
        value: Option<usize>,
        limit: Option<usize>,
    },

𝐓 🚩+ 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: 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

🚩 The operation did not satisfy a finite capacity constraint.

Fields

bound: Boundary1d

Which boundary of the capacity constraint applies.

value: Option<usize>

The value involved in the capacity check, if known.

limit: Option<usize>

The capacity limit involved in the check, if known.

Trait Implementations

impl Clone for TextError

fn clone(&self) -> TextError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TextError

impl Debug for TextError

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

Formats the value using the given formatter.

impl Eq for TextError

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 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.
