Enum SecretstreamError 

pub enum SecretstreamError {
    InvalidLength,
    TagMismatch,
    UnknownTag,
    StreamFinalized,
    Random(RandomError),
}

Variants

InvalidLength

ciphertext_out.len() != plaintext.len() (or the plaintext_out/ciphertext equivalent on PullState::pull).

TagMismatch

Authentication failed: wrong key, wrong header, tampered ciphertext/tag/tag-byte, or a chunk out of sequence (wrong counter) - reordered, dropped, or spliced from another stream.

UnknownTag

tag_byte passed to PullState::pull was not one of the four values Tag::to_byte produces.

StreamFinalized

PushState::push/PullState::pull called again after a Tag::Final chunk already closed this state.

Random(RandomError)

PushState::init’s OS CSPRNG call failed while generating a header.

Trait Implementations

impl Debug for SecretstreamError

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

Formats the value using the given formatter.

impl Display for SecretstreamError

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

Formats the value using the given formatter.

impl Error for SecretstreamError

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<RandomError> for SecretstreamError

Available on crate features getrandom or std only.

fn from(e: RandomError) -> Self

Converts to this type from the input type.
