pub enum FileMetadataError {
    WrongKind(Kind),

    MissingMimeType,
    MissingHash,
    InvalidUrl(UrlError),
    InvalidHash(HexError),

Errors raised by FileMetadata::from_event / FileMetadata::to_tags.

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.

WrongKind(Kind)

The event was not kind: 1063.

MissingUrl

The required url tag is missing.

MissingMimeType

The required m (MIME) tag is missing.

MissingHash

The required x (SHA-256) tag is missing.

InvalidUrl(UrlError)

A URL value did not parse.

InvalidHash(HexError)

A SHA-256 value did not decode as 32 bytes of hex.

InvalidHashLength(usize)

SHA-256 hex was the wrong length.

InvalidSize(String)

The size value did not parse as u64.

InvalidDim(ImageError)

The dim value did not parse as <width>x<height>.

Trait Implementations

impl Debug for FileMetadataError

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

Formats the value using the given formatter.

impl Display for FileMetadataError

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

Formats the value using the given formatter.

impl Error for FileMetadataError

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.
