Enum DispatchError 

pub enum DispatchError {
    OperationNotFound(u8),
    InvalidInput(String),
    UnknownOperationType(String),
    MissingParam {
        op: String,
        param: &'static str,
    },
    InvalidContinuation(usize),
}

Errors returned by selector dispatch.

Variants

OperationNotFound(u8)

No operation was registered for the selector.

InvalidInput(String)

Input was not valid for the selected operation.

UnknownOperationType(String)

TOML config declared an operation type this crate does not know.

MissingParam

TOML config omitted a required parameter.

Fields

op: String

param: &'static str

InvalidContinuation(usize)

Program counter stepped out of the chain.

Trait Implementations

impl Clone for DispatchError

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 DispatchError

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

Formats the value using the given formatter.

impl Display for DispatchError

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

Formats the value using the given formatter.

impl Eq for DispatchError

impl Error for DispatchError

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 DispatchError

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

Equality operator ==.

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

Inequality operator !=.
