Enum PointerError 

pub enum PointerError {
    WrongLength(usize),
    UnknownFormatVersion(u8),
    InvalidOwnerKey(String),
    InvalidSignatureFormat(String),
    SignatureInvalid,
    SigningFailed(String),
    CounterExhausted,
}

Why a pointer was refused.

Display is written by hand rather than derived, because this crate is a wire contract and does not take a macro dependency for it — the same reason crate::error::Error is hand-written.

Variants

WrongLength(usize)

The encoding is not exactly POINTER_WIRE_LEN bytes.

UnknownFormatVersion(u8)

The format version is not one this build understands.

InvalidOwnerKey(String)

The owner key does not decode.

InvalidSignatureFormat(String)

The signature does not decode.

SignatureInvalid

The signature does not verify under the owner key in the record.

SigningFailed(String)

Signing failed.

CounterExhausted

The counter is at FINAL_COUNTER: the pointer is final and no further state can replace it.

Trait Implementations

impl Clone for PointerError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PointerError

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

Formats the value using the given formatter.

impl Display for PointerError

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

Formats the value using the given formatter.

impl Eq for PointerError

impl Error for PointerError

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 PointerError

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

Equality operator ==.

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

Inequality operator !=.
