Enum snow::error::Error

#[non_exhaustive]
pub enum Error {
    Pattern(PatternProblem),
    Init(InitStage),

    Input,
    Dh,

}

All errors in snow will include an ErrorKind.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Pattern(PatternProblem)

The noise pattern failed to parse.

Init(InitStage)

Initialization failure, at a provided stage.

Prereq(Prerequisite)

Missing prerequisite.

State(StateProblem)

A state error.

Input

Invalid input.

Dh

Diffie-hellman failed.

Decrypt

Decryption failed.

Trait Implementations

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

pub fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
