Enum BuildError 

pub enum BuildError {
    SenderKeyMismatch,
    RoleShape(ClaimsError),
    ResponseKeyNotText,
    Rng,
    SealFailed,
    Sign(SignError),
    Codec,
}

Why building a message failed.

Variants

SenderKeyMismatch

The claims’ sender_key_id does not equal the signer’s key id.

RoleShape(ClaimsError)

The claims do not satisfy the declared message role shape.

ResponseKeyNotText

A response_key_id must be UTF-8: the -70004 header is a tstr.

Rng

Randomness was unavailable (nonce / ephemeral generation).

SealFailed

The AEAD seal operation failed (crypto-internal; should not occur for in-range inputs) or the key agreement was non-contributory.

Sign(SignError)

The signer failed.

Codec

Internal structure encoding failed (crypto-internal; should not occur for profile-valid inputs).

Trait Implementations

impl Clone for BuildError

fn clone(&self) -> BuildError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BuildError

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

Formats the value using the given formatter.

impl Display for BuildError

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

Formats the value using the given formatter.

impl Eq for BuildError

impl Error for BuildError

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 From<SignError> for BuildError

fn from(e: SignError) -> Self

Converts to this type from the input type.

impl PartialEq for BuildError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
