Enum PropertiesBufError 

#[non_exhaustive]
pub enum PropertiesBufError {
    DisallowedProperty(PropertyId),
    DuplicateProperty(PropertyId),
    TooLong,
}

Error returned by fallible mutation methods on PropertiesBuf.

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.

DisallowedProperty(PropertyId)

The supplied property’s identifier is not permitted by the PropertyConstraint.

DuplicateProperty(PropertyId)

The buffer already holds a property with this identifier and it may appear at most once (Protocol Error when sent, §2.2.2.2).

TooLong

Appending the property would push the total encoded length above Vbi::MAX.

Trait Implementations

impl Clone for PropertiesBufError

fn clone(&self) -> PropertiesBufError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PropertiesBufError

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

Formats the value using the given formatter.

impl Display for PropertiesBufError

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

Formats the value using the given formatter.

impl Error for PropertiesBufError

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<PropertiesBufError> for Error

fn from(e: PropertiesBufError) -> Self

Converts to this type from the input type.

impl PartialEq for PropertiesBufError

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