Enum Error 

pub enum Error {
    SizeMismatch {
        reference: (usize, usize),
        target: (usize, usize),
    },
    NoSuchReference {
        reference: usize,
        exposures: usize,
    },
}

What can be wrong with a set of exposures.

Only the arguments a caller takes from its own user are reported this way. A buffer whose length contradicts the dimensions passed with it stays a panic, because nothing downstream can do anything about it.

Variants

SizeMismatch

Two exposures are not the same size.

Fields

reference: (usize, usize)

target: (usize, usize)

NoSuchReference

The chosen reference is not one of the exposures.

Fields

reference: usize

exposures: usize

Trait Implementations

impl Clone for Error

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Error

impl Debug for Error

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 Eq for Error

impl Error for Error

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 Error

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
