Enum EncodeError 

#[non_exhaustive]
pub enum EncodeError {
    NoRoom {
        needed: usize,
        available: usize,
    },
    ReservedNetwork,
    EmptySource,
    AddressTooLong,
}

Why Npdu::encode_into refused an NPDU. Nothing was written.

It is #[non_exhaustive], so a new refusal isn’t a breaking change: a match needs a wildcard arm.

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.

NoRoom

The buffer is shorter than the NPDU.

Fields

needed: usize

The NPDU’s length, Npdu::encoded_len.

available: usize

The buffer’s length.

ReservedNetwork

A DNET of 0, or an SNET of 0 or 0xFFFF, which no decoder accepts.

EmptySource

An empty SADR.

AddressTooLong

A DADR or SADR longer than MAX_MAC_LEN.

Trait Implementations

impl Eq for EncodeError

impl Error for EncodeError

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 PartialEq for EncodeError

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

Equality operator ==.

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

Inequality operator !=.
