Enum SmitError 

#[non_exhaustive]
pub enum SmitError {
    TooLong {
        chars: usize,
    },
    Unprintable,
    Empty,
}

Why a string is not a Smit.

#[non_exhaustive]: the grammar can gain a reason to reject, and an out-of-tree consumer matching exhaustively would break on a new variant with no version bump to say so. It buys nothing on the wire. This enum is not serialized: a smit that fails to decode arrives as a serde error carrying the fmt::Display text below.

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.

TooLong

Over Smit::MAX_CHARS characters; carries the count that was sent.

Fields

chars: usize

How many characters the string held.

Unprintable

A control character, \u{1b} included.

Empty

Empty, or nothing but whitespace.

impl Eq for SmitError

impl Error for SmitError

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.
