Enum TryFromError 

#[non_exhaustive]
pub enum TryFromError {
    TypeNotFound(u32),
    VariantExpected(u32),
    UnsupportedMetadataVersion(u32),
    TypeNameNotFound(String),
    InvalidTypePath(String),
    StorageInfoError(StorageInfoError<'static>),

}

An error emitted if something goes wrong converting frame_metadata types into crate::Metadata.

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.

TypeNotFound(u32)

Type missing from type registry

VariantExpected(u32)

Type was not a variant/enum type

UnsupportedMetadataVersion(u32)

An unsupported metadata version was provided.

TypeNameNotFound(String)

Type name missing from type registry

InvalidTypePath(String)

Invalid type path.

StorageInfoError(StorageInfoError<'static>)

Cannot decode storage entry information.

RuntimeInfoError(RuntimeApiInfoError<'static>)

Cannot decode Runtime API information.

ViewFunctionInfoError(ViewFunctionInfoError<'static>)

Cannot decode View Function information.

Trait Implementations

impl Debug for TryFromError

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

Formats the value using the given formatter.

impl Display for TryFromError

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

Formats the value using the given formatter.

impl Eq for TryFromError

impl Error for TryFromError

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<RuntimeApiInfoError<'static>> for TryFromError

fn from(source: RuntimeApiInfoError<'static>) -> Self

Converts to this type from the input type.

impl From<StorageInfoError<'static>> for TryFromError

fn from(source: StorageInfoError<'static>) -> Self

Converts to this type from the input type.

impl From<ViewFunctionInfoError<'static>> for TryFromError

fn from(source: ViewFunctionInfoError<'static>) -> Self

Converts to this type from the input type.

impl PartialEq for TryFromError

fn eq(&self, other: &TryFromError) -> 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.
