Enum KnxError 

pub enum KnxError {
    InvalidAddress(&'static str),
    BufferTooShort {
        needed: usize,
        actual: usize,
    },
    InvalidFrame(&'static str),
    UnsupportedServiceType(u16),
}

Why this crate refused.

Each variant names a class of refusal and carries only what the caller can act on: a static reason for the classes with several causes, the 2 counts for a short read, and the code itself for one this crate does not speak. Nothing here carries owned data, so the type is as usable without std as with it.

Variants

InvalidAddress(&'static str)

Text or parts that do not name an address: a level past the bits it has, a missing part, a part that is not a number, or more parts than the form takes. The reason states which.

BufferTooShort

Input ended before the structure being read does. The read is refused rather than completed from whatever is there.

Fields

needed: usize

How many octets the read needs, counted from the start of the input it was given.

actual: usize

How many octets that input actually holds.

InvalidFrame(&'static str)

A frame that is present but not one this crate can read: a length or version octet disagreeing with what it precedes, a field code outside what is modeled, or a telegram whose service and payload contradict each other. The reason states which.

UnsupportedServiceType(u16)

A well-formed KNXnet/IP service code that is outside the set this crate speaks. The code that arrived is carried, because the refusal is about this crate’s scope rather than about the frame being malformed.

Trait Implementations

impl Clone for KnxError

fn clone(&self) -> KnxError

impl Eq for KnxError

impl Error for KnxError

Available on crate feature std only.

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.
