Enum LinkSourceError 

#[non_exhaustive]
pub enum LinkSourceError {
    Missing,
}

Error returned by Link::validate_source when the source invariant (RFC 8984 §1.4.11 + JMAP Calendars draft §5.3) is violated.

Currently the only failure mode is “neither href nor blob_id is set”; the type is #[non_exhaustive] so additional variants can be added without breaking matches.

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.

Missing

Neither href nor blob_id is set. Per RFC 8984 §1.4.11 href is mandatory; per JMAP Calendars draft §5.3 a blob_id may substitute. At least one of the two MUST be present.

Trait Implementations

impl Clone for LinkSourceError

fn clone(&self) -> LinkSourceError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LinkSourceError

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

Formats the value using the given formatter.

impl Display for LinkSourceError

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

Formats the value using the given formatter.

impl Eq for LinkSourceError

impl Error for LinkSourceError

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 LinkSourceError

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