Enum SchemaMetadataError 

pub enum SchemaMetadataError {
    InvalidVersion,
    EmptyFingerprint,
    FingerprintTooLong,
    NonAsciiFingerprint,
    ControlCharacterFingerprint,
}

SchemaMetadataError

Schema metadata validation failure.

Variants

InvalidVersion

Schema version zero is reserved for absence.

EmptyFingerprint

Present fingerprints must be non-empty.

FingerprintTooLong

Fingerprints must stay bounded for durable ledger storage.

NonAsciiFingerprint

Fingerprints must not require Unicode normalization.

ControlCharacterFingerprint

Fingerprints must be printable metadata.

Trait Implementations

impl Clone for SchemaMetadataError

fn clone(&self) -> SchemaMetadataError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SchemaMetadataError

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

Formats the value using the given formatter.

impl Display for SchemaMetadataError

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

Formats the value using the given formatter.

impl Error for SchemaMetadataError

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 SchemaMetadataError

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