Error variants for fallible Crockford Base32 operations.

Variants

BufferTooSmall

The buffer size is insufficient for the operation.

Fields

• min - The minimum required buffer size.
• len - The actual size of the provided buffer.

Fields

min: usize

len: usize

InvalidDataSize

The input data size doesn’t match the expected size.

Fields

• expected - The expected data size in bytes.
• got - The actual size of the provided data.

Fields

expected: usize

got: usize

InvalidCharacter

An invalid character was encountered during decoding.

Fields

• char - The invalid character found in the input.
• index - The byte index of the character.

Fields

char: char

index: usize

MissingPrefix

The expected prefix character is missing.

Fields

• char - The expected prefix character.
• got - The actual first character found.

Fields

char: char

got: Option<char>

InvalidVersion

Available on crate feature check only.

The provided version byte is invalid.

Fields

• expected - The expected version constraints.
• version - The invalid version byte.

Fields

expected: &'static str

version: u8

InsufficientData

Available on crate feature check only.

The input has fewer bytes than are required.

Fields

• min - The minimum required amount of bytes.
• len - The actual number of bytes provided.

Fields

min: usize

len: usize

ChecksumMismatch

Available on crate feature check only.

The computed checksum does not match the expected sum.

Fields

• expected - The expected checksum.
• got - The actual checksum.

Fields

got: Checksum

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

const 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 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 Hash for Error

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Error

fn cmp(&self, other: &Error) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Error

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

Tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Error

fn partial_cmp(&self, other: &Error) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
