Enum DecodeError 

#[non_exhaustive]
pub enum DecodeError {
    Overflow,
    InsufficientData(InsufficientData),
    Other(Cow<'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(Cow<'static, str>)

Available on crate features alloc or std only.

A custom error message.

Implementations

impl DecodeError

pub const fn overflow() -> DecodeError

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

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

Creates a new DecodeError::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, ) -> DecodeError

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

Panics

Panics if required is not greater than available.

pub fn other(msg: impl Into<Cow<'static, str>>) -> DecodeError

Available on crate features alloc or std only.

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

Trait Implementations

impl Clone for DecodeError

fn clone(&self) -> DecodeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DecodeError

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

Formats the value using the given formatter.

impl Display for DecodeError

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

Formats the value using the given formatter.

impl Eq for DecodeError

impl Error for DecodeError

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(err: ConstDecodeError) -> DecodeError

Converts to this type from the input type.

impl From<DecodeError> for DecodeError

fn from(e: DecodeError) -> DecodeError

Converts to this type from the input type.

impl From<DecodeError> for Error

Available on crate feature std only.

fn from(err: DecodeError) -> Error

Converts to this type from the input type.

impl From<InsufficientData> for DecodeError

fn from(source: InsufficientData) -> DecodeError

Converts to this type from the input type.

impl Hash for DecodeError

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 DecodeError

fn eq(&self, other: &DecodeError) -> 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.
