Enum Error 

pub enum Error {
    UnexpectedEnd,
    UnexpectedByte {
        offset: usize,
        byte: u8,
    },
    InvalidInteger {
        offset: usize,
    },
    IntegerOverflow {
        offset: usize,
    },
    InvalidLength {
        offset: usize,
    },
    UnsortedOrDuplicateKey {
        offset: usize,
    },
    NonStringKey {
        offset: usize,
    },
    TrailingData {
        offset: usize,
    },
}

A typed parse failure. Every malformed-stream condition is one of these — the AST is never built from invalid bytes.

Variants

UnexpectedEnd

The stream ended mid-value.

UnexpectedByte

A byte that can’t begin a value (not i/l/d/digit), with its offset.

Fields

offset: usize

byte: u8

InvalidInteger

An integer with a leading zero (i03e), a bare/negative zero (i-0e), or non-digit body.

Fields

offset: usize

IntegerOverflow

An integer that overflows i64.

Fields

offset: usize

InvalidLength

A byte-string length that isn’t valid base-10 or overruns the buffer.

Fields

offset: usize

UnsortedOrDuplicateKey

A dict whose keys are out of order or duplicated (canonical parsing requires strictly-ascending unique keys).

Fields

offset: usize

NonStringKey

A dict key that wasn’t a byte string.

Fields

offset: usize

TrailingData

parse found valid trailing bytes after a complete value.

Fields

offset: usize

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for 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.

impl PartialEq for Error

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