Enum SexpError 

pub enum SexpError {
    Type(SexpTypeError),
    Length(SexpLengthError),
    Na(SexpNaError),
    InvalidValue(String),
    MissingField(String),
    DuplicateName(String),
}

Unified conversion error when decoding an R SEXP.

Variants

Type(SexpTypeError)

SEXPTYPE did not match the expected one.

Length(SexpLengthError)

Length did not match the expected one.

Na(SexpNaError)

Missing value encountered where disallowed.

InvalidValue(String)

Value is syntactically valid but semantically invalid (e.g. parse error).

MissingField(String)

A required field was missing from a named list.

DuplicateName(String)

A named list has duplicate non-empty names.

Trait Implementations

impl Clone for SexpError

fn clone(&self) -> SexpError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SexpError

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

Formats the value using the given formatter.

impl Display for SexpError

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

Formats the value using the given formatter.

impl Error for SexpError

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 From<MatchArgError> for SexpError

fn from(e: MatchArgError) -> Self

Converts to this type from the input type.

impl From<SexpLengthError> for SexpError

fn from(e: SexpLengthError) -> Self

Converts to this type from the input type.

impl From<SexpNaError> for SexpError

fn from(e: SexpNaError) -> Self

Converts to this type from the input type.

impl From<SexpTypeError> for SexpError

fn from(e: SexpTypeError) -> Self

Converts to this type from the input type.
