Struct InsufficientData 

pub struct InsufficientData { /* private fields */ }

An error that occurs when trying to decode data from a buffer with insufficient data.

This error indicates that a decode operation failed because the buffer does not have enough remaining bytes to decode the value.

Implementations

impl InsufficientData

pub const fn new(available: usize) -> InsufficientData

Creates a new InsufficientData error with only the available bytes.

pub const fn with_required( required: NonZero<usize>, available: usize, ) -> InsufficientData

Creates a new InsufficientData error with the required and available bytes.

Panics

Panics if required is not greater than available.

pub const fn required(&self) -> Option<NonZero<usize>>

Returns the number of bytes required to decode the value, if known.

pub const fn available(&self) -> usize

Returns the number of bytes available in the buffer.

Trait Implementations

impl Clone for InsufficientData

fn clone(&self) -> InsufficientData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for InsufficientData

impl Debug for InsufficientData

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

Formats the value using the given formatter.

impl Display for InsufficientData

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

Formats the value using the given formatter.

impl Eq for InsufficientData

impl Error for InsufficientData

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<InsufficientData> for ConstDecodeError

fn from(source: InsufficientData) -> ConstDecodeError

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 InsufficientData

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 InsufficientData

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