Enum Error 

pub enum Error<E = !> {
    Stream(usize, E),
    Unexpected(usize, Option<char>),
    InvalidUnicodeCodePoint(Span, u32),
    MissingLowSurrogate(Span, u32),
    InvalidLowSurrogate(Span, u32, u32),
    InvalidUtf8(usize),
}

Parse error.

Variants

Stream(usize, E)

Stream error.

The first parameter is the byte index at which the error occurred.

Unexpected(usize, Option<char>)

Unexpected character or end of stream.

The first parameter is the byte index at which the error occurred.

InvalidUnicodeCodePoint(Span, u32)

Invalid unicode codepoint.

The first parameter is the span at which the error occurred.

MissingLowSurrogate(Span, u32)

Missing low surrogate in a string.

The first parameter is the byte index at which the error occurred.

InvalidLowSurrogate(Span, u32, u32)

Invalid low surrogate in a string.

The first parameter is the span at which the error occurred.

InvalidUtf8(usize)

UTF-8 encoding error.

Implementations

impl<E> Error<E>

pub const fn position(&self) -> usize

Returns the byte position at which the error occurred.

pub fn span(&self) -> Span

Returns the byte span the error covers.

Errors that point at a single position return an empty span there.

Trait Implementations

impl<E> Debug for Error<E>

where E: Debug,

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

Formats the value using the given formatter.

impl<E> Display for Error<E>

where E: Display,

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

Formats the value using the given formatter.

impl<E> Error for Error<E>

where E: 'static + Error,

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.
