Enum AttributeSemanticError 

pub enum AttributeSemanticError {
    InvalidEntry,
    NameMismatch,
    AlreadyExists,
    Missing,
    StateConflict,
}

Attribute mutation semantic failures.

Variants

InvalidEntry

Entry references a non-blob payload.

NameMismatch

Mutation precondition and replacement names differ.

AlreadyExists

Insert expected an absent name.

Missing

Remove or replace expected an existing name.

StateConflict

Existing complete entry differs from the precondition.

impl Eq for AttributeSemanticError

impl Error for AttributeSemanticError

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
