Enum SubnetError 

pub enum SubnetError {
    LevelOutOfRange {
        got: u8,
    },
    LevelValueReserved,
    TooManyLevels {
        got: usize,

}

Validation error returned by the fallible subnet constructors.

Variants

LevelOutOfRange

Hierarchy level is outside [0, 3].

Returned by super::SubnetPolicy::try_add_rule.

Fields

got: u8

The out-of-range level value the caller supplied.

LevelValueReserved

level_value == 0 is reserved for “unmatched / no restriction at this level” and must not appear as an explicit mapping.

Returned by super::SubnetRule::try_map.

TooManyLevels

More hierarchy levels were supplied than the encoding supports (MAX_DEPTH = 4).

Returned by super::SubnetId::try_new.

Fields

got: usize

Number of levels the caller supplied.

max: u8

Hard cap from super::id::MAX_DEPTH.

ParseFailed

String form did not parse as a super::SubnetId.

Returned by SubnetId::from_str. Carries the original input and a short reason so the operator sees what rejected the value.

Fields

input: String

The string the caller supplied.

reason: String

Short human-readable reason for the rejection.

Trait Implementations

impl Clone for SubnetError

fn clone(&self) -> SubnetError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SubnetError

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

Formats the value using the given formatter.

impl Display for SubnetError

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

Formats the value using the given formatter.

impl Eq for SubnetError

impl Error for SubnetError

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 SubnetError

fn eq(&self, other: &SubnetError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
