Enum HookError 

#[non_exhaustive]
pub enum HookError {
    NotLoaded(Vec<Address>),
    NoList,
    MalformedMint,
    Unresolvable(Unresolvable),
}

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(Vec<Address>)

The mint infos do not hold these accounts. Fetch them. Insert them into a copy of each mint info. Build again until the build does not return 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.

MalformedMint

A mint in a HookState is not a mint that a token program owns, or its extensions do not decode. HookState::missing gives it.

Unresolvable(Unresolvable)

Trait Implementations

impl Clone for HookError

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 HookError

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

Formats the value using the given formatter.

impl Display for HookError

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

Formats the value using the given formatter.

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 From<HookError> for Unroutable

fn from(error: HookError) -> Self

Converts to this type from the input type.

impl From<HookError> for BuildError

fn from(error: HookError) -> Self

Converts to this type from the input type.

impl From<Unresolvable> for HookError

fn from(reason: Unresolvable) -> Self
