Struct ParseError

pub struct ParseError {
    pub start_loc: usize,
    pub end_loc: Option<usize>,
    pub err: ParseErrorKind,
}

An error parsing the provided string into a Value

Fields

start_loc: usize

Byte offset into the provided string that the error begins.

end_loc: Option<usize>

Byte offset into the provided string that the error ends. Many errors begin at some point but do not have a known end position.

err: ParseErrorKind

Details about the error that occurred.

Implementations

impl ParseError

pub fn new_at<E: Into<ParseErrorKind>>(err: E, loc: usize) -> Self

Construct a new ParseError for tokens at the given location.

pub fn new_between<E: Into<ParseErrorKind>>( err: E, start: usize, end: usize, ) -> Self

Construct a new ParseError for tokens between the given locations.

Trait Implementations

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, f: &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 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.
