Enum ExpandMsgXmdError 

pub enum ExpandMsgXmdError {
    EmptyDst,
    DstHash,
    Length,
}

Error type for ExpandMsgXmd.

Variants

EmptyDst

The domain separation tag must not be empty.

DstHash

The hash’s output size must not be greater then 255 if the domain separation tag is longer than 255.

Length

The length in bytes is too large.

len_in_bytes must be at most 255 * HashT::OutputSize.

Trait Implementations

impl Clone for ExpandMsgXmdError

fn clone(&self) -> ExpandMsgXmdError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExpandMsgXmdError

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

Formats the value using the given formatter.

impl Display for ExpandMsgXmdError

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

Formats the value using the given formatter.

impl Error for ExpandMsgXmdError

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 PartialEq for ExpandMsgXmdError

fn eq(&self, other: &ExpandMsgXmdError) -> 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.
