Enum SExprError 

pub enum SExprError {
    Parse(String),
    Shape(String),
    MissingField(String),
    UnknownVariant(String),
}

Conversion errors during FromSExpr parsing.

Variants

Parse(String)

Top-level parse failure (bad tokens, unbalanced parens, etc.).

Shape(String)

Value shape didn’t match what the destination type expected.

MissingField(String)

A named field required by the destination was missing.

UnknownVariant(String)

Unknown / unsupported variant tag.

Trait Implementations

impl Clone for SExprError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SExprError

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

Formats the value using the given formatter.

impl Display for SExprError

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

Formats the value using the given formatter.

impl Eq for SExprError

impl Error for SExprError

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.
