Enum LinkError 

pub enum LinkError {
    MultipleValues,
    NoValue,
    ValueMismatch,
    Invalid,
}

Error derived from contract linking validation procedure

Variants

MultipleValues

Contract links to more than one Contract ID

NoValue

Contract does not link to a Contract ID

ValueMismatch

Link between parent and child contract is broken

Invalid

Value is not a valid Contract ID

Trait Implementations

impl Clone for LinkError

fn clone(&self) -> LinkError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LinkError

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

Formats the value using the given formatter.

impl Display for LinkError

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

Formats the value using the given formatter.

impl Error for LinkError

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<S, H, P, E> From<LinkError> for StockError<S, H, P, E>

where S: StashProvider, H: StateProvider, P: IndexProvider, E: Error,

fn from(v: LinkError) -> StockError<S, H, P, E>

Converts to this type from the input type.

impl From<LinkError> for String

fn from(err: LinkError) -> String

Converts to this type from the input type.

impl PartialEq for LinkError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
