Enum ConstDecodeError 

#[non_exhaustive]
pub enum ConstDecodeError {
    Overflow,
    InsufficientData(InsufficientData),
    Other(&'static str),
}

Decoding varint error.

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.

Overflow

The buffer does not contain a valid LEB128 encoding.

InsufficientData(InsufficientData)

The buffer does not contain enough data to decode.

Other(&'static str)

A custom error message.

Implementations

impl ConstDecodeError

pub const fn overflow() -> ConstDecodeError

Creates a new ConstDecodeError::Overflow indicating that the decoded value would overflow the target type.

pub const fn insufficient_data(available: usize) -> ConstDecodeError

Creates a new ConstDecodeError::InsufficientData indicating that the buffer does not have enough data to decode a value.

pub const fn insufficient_data_with_required( required: NonZero<usize>, available: usize, ) -> ConstDecodeError

Creates a new ConstDecodeError::InsufficientData with the required and available bytes.

Panics

Panics if required is not greater than available.

pub const fn other(msg: &'static str) -> ConstDecodeError

Creates a new ConstDecodeError::Other with the given message.

pub const fn into_decode_error(self) -> DecodeError

Converts this ConstDecodeError into a DecodeError.

Example

use varing::{ConstDecodeError, DecodeError};

let const_error = ConstDecodeError::other("Other error message");
let error: DecodeError = const_error.into_decode_error();

let const_error_overflow = ConstDecodeError::overflow();
let error_overflow: DecodeError = const_error_overflow.into_decode_error();

let const_error_insufficient = ConstDecodeError::insufficient_data(5);
let error_insufficient: DecodeError = const_error_insufficient.into_decode_error();

Trait Implementations

impl Clone for ConstDecodeError

fn clone(&self) -> ConstDecodeError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ConstDecodeError

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Display for ConstDecodeError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Eq for ConstDecodeError

impl Error for ConstDecodeError

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 From<ConstDecodeError> for DecodeError

fn from(e: ConstDecodeError) -> DecodeError

Converts to this type from the input type.

impl From<ConstDecodeError> for Error

Available on crate feature std only.

fn from(err: ConstDecodeError) -> Error

Converts to this type from the input type.

impl From<ConstDecodeError> for DecodeError

fn from(err: ConstDecodeError) -> DecodeError

Converts to this type from the input type.

impl From<InsufficientData> for ConstDecodeError

fn from(source: InsufficientData) -> ConstDecodeError

Converts to this type from the input type.

impl Hash for ConstDecodeError

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

where __H: Hasher,

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 PartialEq for ConstDecodeError

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

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

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

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