pub enum InvalidReason {
    Empty,
    TooLong {
        actual: usize,
        maximum: usize,
    },
}

Why construction of a cancellation reason failed.

Variants

TooLong

The reason exceeded the fixed memory and disclosure bound.

Fields

actual: usize

Supplied UTF-8 byte count.

maximum: usize

Accepted UTF-8 byte count.

Trait Implementations

impl Clone for InvalidReason

fn clone(&self) -> InvalidReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InvalidReason

impl Eq for InvalidReason

impl Error for InvalidReason

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 InvalidReason

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

Equality operator ==.

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

Inequality operator !=.
