Struct SexpTypeError 

pub struct SexpTypeError {
    pub expected: SEXPTYPE,
    pub actual: SEXPTYPE,
}

Error describing an unexpected R SEXPTYPE.

Fields

expected: SEXPTYPE

Expected R type.

actual: SEXPTYPE

Actual R type encountered.

Implementations

impl SexpTypeError

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

The reason of this type error in R terms (#1591): got character, or expected integer, got character when expected_known is false (nothing before the reason says what the value should be). The type names are sexptype_name’s (numeric for a double, list, NULL, …), not SEXPTYPE names.

A pairlist where a list was expected says how to fix it: got pairlist, convert it with as.list(). R’s is.list() is TRUE for a pairlist, but a list conversion refuses one (#1866).

#[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<SexpTypeError> for SexpError

fn from(e: SexpTypeError) -> 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.
