Struct SexpClassError 

pub struct SexpClassError {
    pub expected: &'static str,
    pub actual: SEXPTYPE,
}

Error describing a value that is not the kind of R object a conversion reads, where that kind is a class rather than a SEXPTYPE (a data frame is a list with a class).

Fields

expected: &'static str

What the value should have been, in R terms, with its article: "a data frame".

actual: SEXPTYPE

Actual R type encountered.

Implementations

impl SexpClassError

pub(crate) fn r_reason(&self, expected_known: bool) -> String

The reason of this class error in R terms: got list, or expected a data frame, got list when expected_known is false.

Trait Implementations

impl Clone for SexpClassError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ConversionErrBuiltin for SexpClassError

fn __mx_conversion_parts(&self, expected_known: bool) -> ErrParts

impl Copy for SexpClassError

impl Debug for SexpClassError

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

Formats the value using the given formatter.

impl Display for SexpClassError

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

Formats the value using the given formatter.

impl Error for SexpClassError

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

#[doc(hidden)]

fn type_id(&self, _: Internal) -> TypeId

where Self: 'static,

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

Gets the TypeId of self.

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 From<SexpClassError> for SexpError

fn from(e: SexpClassError) -> Self

Converts to this type from the input type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
