Enum Error

pub enum Error<'a> {
    ErrorKind {
        input: &'a BStr,
        kind: ErrorKind,
    },
    ErrorWithContexts(Vec<ParseTypeContext<'a>>),
}

Error type used by FromSql.

Keeps a list of the items that were being parsed when an error was encountered. The Display implementation prints a backtrace with a snippet of the text that failed to parse.

Trait Implementations

impl<'a> Clone for Error<'a>

fn clone(&self) -> Error<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> ContextError<&'a [u8]> for Error<'a>

fn add_context(input: &'a [u8], label: &'static str, other: Self) -> Self

Creates a new error from an input position, a static string and an existing error. This is used mainly in the context combinator, to add user friendly information to errors when backtracking through a parse tree

impl<'a> Debug for Error<'a>

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

Formats the value using the given formatter.

impl<'a> Display for Error<'a>

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

Formats the value using the given formatter.

impl<'a, I: Into<&'a [u8]>, E> FromExternalError<I, E> for Error<'a>

fn from_external_error(input: I, kind: ErrorKind, _e: E) -> Self

Creates a new error from an input position, an ErrorKind indicating the wrapping parser, and an external error

impl<'a> ParseError<&'a [u8]> for Error<'a>

fn from_error_kind(input: &'a [u8], kind: ErrorKind) -> Self

Creates an error from the input position and an ErrorKind

fn append(input: &'a [u8], kind: ErrorKind, other: Self) -> Self

Combines an existing error with a new one created from the input position and an ErrorKind. This is useful when backtracking through a parse tree, accumulating error context on the way

fn from_char(input: &'a [u8], _: char) -> Self

Creates an error from an input position and an expected character

fn or(self, other: Self) -> Self

Combines two existing errors. This function is used to compare errors generated in various branches of alt.

impl<'a> PartialEq for Error<'a>

fn eq(&self, other: &Error<'a>) -> 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.
