Enum StreamError 

pub enum StreamError {
    Truncated,
    Random(RandomError),
}

crypto_stream can fail only if the OS CSPRNG fails while generating a fresh IV - there is no tag to mismatch (see the module doc’s “No authentication” section).

Variants

Truncated

The input to decrypt is shorter than an IV (32 bytes) - too short to have ever been produced by encrypt.

Random(RandomError)

The OS CSPRNG failed while generating an IV (see crate::randombytes).

Trait Implementations

impl Debug for StreamError

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

Formats the value using the given formatter.

impl Display for StreamError

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

Formats the value using the given formatter.

impl Error for StreamError

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 StreamError

fn from(e: RandomError) -> Self

Converts to this type from the input type.
