}

The concrete reason why a JSON document was rejected lexically.

This enum intentionally remains exhaustive so callers can classify every documented lexical rejection at compile time. New reasons require a breaking release rather than a #[non_exhaustive] change.

Examples

use qubit_json::decode::JsonSyntaxErrorReason;

let reason = JsonSyntaxErrorReason::UnexpectedByte;
assert_eq!(reason.to_string(), "unexpected byte");

Variants

UnexpectedEnd

The document ended before a complete token or container was found.

UnexpectedByte

A byte is not valid at the current JSON position.

The byte itself is intentionally not retained, so default structured diagnostics never expose input content.

ExpectedColon

An object key was not followed by a colon.

ExpectedCommaOrArrayEnd

An array value was not followed by a comma or closing bracket.

ExpectedCommaOrObjectEnd

An object value was not followed by a comma or closing brace.

ExpectedObjectKey

An object key was expected at the current position.

InvalidEscape

A string escape sequence is invalid.

InvalidUnicodeEscape

A Unicode escape does not contain four hexadecimal digits.

UnpairedSurrogate

A Unicode surrogate pair is malformed.

InvalidUtf8

The input contains invalid UTF-8.

InvalidNumber

A number does not follow JSON number grammar.

IntegerOutOfRange

An integer is outside the supported i64/u64 range.

FloatOutOfRange

A number is outside the finite f64 range for the selected number model.

TrailingCharacters

Non-whitespace bytes follow the complete root value.

NestingOverflow

A nesting or position counter overflowed.
