Enum PrincipalFactError 

pub enum PrincipalFactError {
    InvalidName,
    InvalidValue,
    LimitExceeded,
    Duplicate,
    InvalidEncoding,
}

Safe failure to construct a bounded principal-fact set.

Variants

InvalidName

A fact name is not a compiler-visible source identifier.

InvalidValue

A fact value is not one scalar or one bounded scalar set.

LimitExceeded

A count or encoded byte ceiling was exceeded.

Duplicate

A fact or set member occurs more than once.

InvalidEncoding

Canonical encoding failed or overflowed.

impl Eq for PrincipalFactError

impl Error for PrincipalFactError

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.
