Enum Base32Error 

#[non_exhaustive]
pub enum Base32Error {
    InvalidBase32,
    #[non_exhaustive]
    InvalidLength {
        expected: usize,
        got: usize,
    },
}

Errors from Base32 (RFC 4648 §6, uppercase, unpadded) decoding. Variant shapes are identical in debug and release builds; only numeric length metadata is carried. Errors produced when decoding Base32 (RFC 4648 §6, uppercase, unpadded) strings.

Requires feature encoding-base32.

Variant shapes are identical in debug and release builds; only numeric length metadata is carried.

The std::error::Error impl requires the std feature. Without it the type still exists and still implements Display, but it is not an Error, so ? into Box<dyn Error> and std::io::Error::other will not compile. This is an MSRV consequence, not a policy: core::error::Error needs Rust 1.81 and this line targets 1.70. On 0.9.x the impl is unconditional and available in no_std.

Variants (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.

InvalidBase32

The string is not valid Base32 (wrong alphabet, wrong case, padding, or an impossible length).

#[non_exhaustive]

InvalidLength

The decoded payload length does not match the target type’s length.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

expected: usize

Number of bytes the target type requires.

got: usize

Number of bytes actually decoded.
