Enum HookError 

#[non_exhaustive]
pub enum HookError {
    NotLoaded,
    NoList,
    Unresolvable(Unresolvable),
    Clash(Clash),
}

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.

NotLoaded

NoList

The validation account is missing, or the hook program does not own it. Token-2022 still calls the hook, and the transfer fails.

Unresolvable(Unresolvable)

Clash(Clash)

A clash of this swap only, for example with this trader’s accounts.

impl Eq for HookError

impl Error for HookError

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 HookError

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

Equality operator ==.

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

Inequality operator !=.
