Enum SamplesError 

pub enum SamplesError {
    Mismatch {
        what: &'static str,
        given: usize,
        n: usize,
    },
}

Why that is not one key per sample.

Variants

Mismatch

As many keys as samples, and there were not.

Fields

what: &'static str

classes or groups.

given: usize

How many arrived.

n: usize

How many there are.

Trait Implementations

impl Clone for SamplesError

fn clone(&self) -> SamplesError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SamplesError

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

Formats the value using the given formatter.

impl Display for SamplesError

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

Formats the value using the given formatter.

impl Error for SamplesError

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 SamplesError

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