Enum CallKeyError 

pub enum CallKeyError {
    Empty,
    TooLong {
        length: usize,
    },
    InvalidCharacter {
        index: usize,
    },
}

Why a call_key was refused.

Variants

Empty

The key was the empty string. An absent key is None, never "".

TooLong

The key was longer than CALL_KEY_MAX_LEN bytes.

Fields

length: usize

InvalidCharacter

The byte at index is not printable, non-space ASCII.

Fields

index: usize

Implementations

impl CallKeyError

pub fn field(&self) -> &'static str

The request field the error is about, always CALL_KEY_FIELD.

Trait Implementations

impl Clone for CallKeyError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CallKeyError

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

Formats the value using the given formatter.

impl Display for CallKeyError

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

Formats the value using the given formatter.

impl Eq for CallKeyError

impl Error for CallKeyError

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 CallKeyError

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

Equality operator ==.

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

Inequality operator !=.
