Enum ExtrinsicParamsError 

#[non_exhaustive]
pub enum ExtrinsicParamsError {
    MissingTypeId {
        type_id: u32,
        context: &'static str,
    },
    UnknownTransactionExtension(String),
    Custom(Box<dyn Error + Send + Sync + 'static>),
}

An error that can be emitted when trying to construct an instance of crate::config::ExtrinsicParams, encode data from the instance, or match on signed extensions.

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.

MissingTypeId

Cannot find a type id in the metadata. The context provides some additional information about the source of the error (eg the signed extension name).

Fields

type_id: u32

Type ID.

context: &'static str

Some arbitrary context to help narrow the source of the error.

UnknownTransactionExtension(String)

A signed extension in use on some chain was not provided.

Custom(Box<dyn Error + Send + Sync + 'static>)

Some custom error.

Implementations

impl ExtrinsicParamsError

pub fn custom<S: Into<String>>(error: S) -> Self

Create a custom ExtrinsicParamsError from a string.

Trait Implementations

impl Debug for ExtrinsicParamsError

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

Formats the value using the given formatter.

impl Display for ExtrinsicParamsError

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

Formats the value using the given formatter.

impl Error for ExtrinsicParamsError

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.
