Enum subxt_metadata::TryFromError

#[non_exhaustive]
pub enum TryFromError {
    TypeNotFound(u32),
    VariantExpected(u32),
    UnsupportedMetadataVersion(u32),
}

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.
