Enum IntoRError 

pub enum IntoRError {
    StringTooLong {
        len: usize,
    },
    LengthOverflow {
        len: usize,
    },
    Inner(String),
}

Error returned by IntoR::try_into_sexp for types whose conversion to R can fail.

Variants

• StringTooLong — a Rust string exceeds R’s i32 length limit (~2 GB)
• LengthOverflow — a collection length exceeds R’s R_xlen_t capacity
• Inner — a sub-conversion failed (wraps the inner error message)

Variants

StringTooLong

A string’s byte length exceeds i32::MAX.

Fields

len: usize

Actual byte length of the string.

LengthOverflow

A collection’s element count exceeds the target R vector capacity.

Fields

len: usize

Actual element count.

Inner(String)

A nested conversion failed.

Trait Implementations

impl Clone for IntoRError

fn clone(&self) -> IntoRError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IntoRError

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

Formats the value using the given formatter.

impl Display for IntoRError

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

Formats the value using the given formatter.

impl Error for IntoRError

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

Returns the lower-level source of this error, if any.

#[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.

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.
