Enum StringErrorKind 

#[non_exhaustive]
pub enum StringErrorKind {
    Primitive(PrimitiveError),
    InvalidUtf8 {
        source: Utf8Error,
    },
    UnexpectedNull,
    NegativeLength {
        length: i32,
    },
    TooLong {
        length: usize,
        max: usize,
    },
}

Specific reason a string read/write failed.

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.

Primitive(PrimitiveError)

Underlying primitive read failed (length prefix or bytes).

InvalidUtf8

String bytes are not valid UTF-8.

Fields

source: Utf8Error

UTF-8 validation failure.

UnexpectedNull

Non-nullable variant got the null marker (negative length / 0 varint).

NegativeLength

Length prefix is negative on a non-nullable encoding.

Fields

length: i32

The negative length read.

TooLong

String length exceeds the maximum encodable length.

Fields

length: usize

Offending length: the value being encoded, or usize::MAX as a sentinel when a wire length prefix did not fit in usize.

max: usize

Protocol-constant maximum (e.g. i32::MAX), not a tunable.

Trait Implementations

impl Debug for StringErrorKind

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

Formats the value using the given formatter.

impl Display for StringErrorKind

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

Formats the value using the given formatter.

impl Error for StringErrorKind

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<PrimitiveError> for StringErrorKind

fn from(source: PrimitiveError) -> Self

Converts to this type from the input type.

impl From<StringErrorKind> for StringError

fn from(kind: StringErrorKind) -> Self

Converts to this type from the input type.
