Enum Base32Error 

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

Available on crate feature encoding-base32 only.

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.

Implements core::error::Error unconditionally — no std feature is required, and the impl is present in no_std builds. (On the 0.8 line this impl is std-gated, because core::error::Error needs Rust 1.81 and that branch targets 1.70. Code that must build against both should not assume the trait is available without 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.

impl Eq for Base32Error

impl Error for Base32Error

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
