Expand description

Error code during parsing, indicating failure type.

Variants (Non-exhaustive)

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Overflow(usize)

Integral overflow occurred during numeric parsing.

Underflow(usize)

Integral underflow occurred during numeric parsing.

InvalidDigit(usize)

Invalid digit found before string termination.

Empty(usize)

Empty byte array found.

EmptyMantissa(usize)

Empty mantissa found.

EmptyExponent(usize)

Empty exponent found.

EmptyInteger(usize)

Empty integer found.

EmptyFraction(usize)

Empty fraction found.

InvalidPositiveMantissaSign(usize)

Invalid positive mantissa sign was found.

MissingMantissaSign(usize)

Mantissa sign was required(usize), but not found.

InvalidExponent(usize)

Exponent was present but not allowed.

InvalidPositiveExponentSign(usize)

Invalid positive exponent sign was found.

Integer or integer component of float had invalid leading zeros.

MissingExponent(usize)

No exponent with required exponent notation.
