Struct ed25519_dalek::errors::DecodingError

pub struct DecodingError(_);

Errors which may occur in the from_bytes() constructors of PublicKey, SecretKey, ExpandedSecretKey, Keypair, and Signature.

There was an internal problem due to parsing the Signature.

This error may arise due to:

• A problem decompressing r, a curve point, in the Signature, or the curve point for a PublicKey.
• A problem with the format of s, a scalar, in the Signature. This is only raised if the high-bit of the scalar was set. (Scalars must only be constructed from 255-bit integers.)
• Being given bytes with a length different to what was expected.

Trait Implementations

impl Clone for DecodingError

fn clone(&self) -> DecodingError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for DecodingError

impl Eq for DecodingError

impl PartialEq for DecodingError

fn eq(&self, __arg_0: &DecodingError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &DecodingError) -> bool

This method tests for !=.

impl Hash for DecodingError

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl Debug for DecodingError

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Display for DecodingError

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

Formats the value using the given formatter.

impl Fail for DecodingError

fn cause(&self) -> Option<&Fail>

Returns a reference to the underlying cause of this failure, if it is an error that wraps other errors.

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

Returns a reference to the Backtrace carried by this failure, if it carries one.

fn context<D>(self, context: D) -> Context<D> where
    D: Display + Send + Sync + 'static, 

Provides context for this failure.

fn compat(self) -> Compat<Self>

Wraps this failure in a compatibility wrapper that implements std::error::Error.

fn causes(&self) -> Causes

Returns a iterator over the causes of this Fail with itself as the first item and the root_cause as the final item.

fn root_cause(&self) -> &(Fail + 'static)

Returns the "root cause" of this Fail - the last value in the cause chain which does not return an underlying cause.
