Enum SealError 

pub enum SealError {
    UnknownSuite(String),
    MalformedEncoding(&'static str),
    MalformedKey(&'static str),
    OpenRefused,
    SealFailed(String),
}

This crate’s own refusals — deliberately NOT APH_E codes (RFC 0008 §5: the §11 set is closed, and names are minted by the version that can declare them, not by a draft).

Variants

UnknownSuite(String)

The payload names a suite this implementation does not compile. One suite, no negotiation — an unknown value is refused, never skipped.

MalformedEncoding(&'static str)

A base64url field would not decode; malformed before cryptography.

MalformedKey(&'static str)

A key was not the KEM’s serialized length/shape.

OpenRefused

AEAD open failed: the wrong key, a tampered ciphertext, or — the case the AAD exists for — a seal lifted from a different envelope. All three are indistinguishable BY DESIGN (that is what AEAD promises), so the refusal names all three rather than guessing.

SealFailed(String)

The HPKE encapsulation step itself failed (a malformed reader key surfaces here when it parses but cannot be used).

Trait Implementations

impl Debug for SealError

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

Formats the value using the given formatter.

impl Display for SealError

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

Formats the value using the given formatter.

impl Eq for SealError

impl Error for SealError

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 SealError

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

Equality operator ==.

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

Inequality operator !=.
