Enum ParseError

pub enum ParseError {
    InvalidChar {
        byte: u8,
        position: usize,
    },
    WrongLength {
        expected: u8,
        got: usize,
    },
}

Error creating an SqlState, Class or Category.

Variants

InvalidChar

The byte at index position in the string was not a valid ASCII character in the range A-Z,0-9.

Fields

byte: u8

position: usize

WrongLength

The source string didn’t have the expected length.

Fields

expected: u8

got: usize

Implementations

impl ParseError

pub const fn valid_up_to(&self) -> usize

Returns the index of the first invalid byte, the position of the premature end or of the first superfluous byte.

if let Err(error) = SqlState::from_str("000!0") {
  let index = error.valid_up_to();
  assert_eq!(index, 3);
} else {
  unreachable!("this is no valid SQLSTATE code");
}

Trait Implementations

impl Clone for ParseError

fn clone(&self) -> ParseError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Error for ParseError

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<ParseError> for Error

fn from(error: ParseError) -> Self

Converts a ParseError to an std::io::Error of kind InvalidData for convenience.

impl PartialEq for ParseError

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