Enum jaq_interpret::error::Error

#[non_exhaustive]
pub enum Error {
    Val(Val),
    Type(Val, Type),
    MathOp(Val, MathOp, Val),
    Index(Val, Val),
    IndexOutOfBounds(isize),
    PathExp,
    TailCall(TailCall),
}

Errors that can occur during filter execution.

Each variant shows an example of how it can be produced.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Val(Val)

0 | error

Type(Val, Type)

Expected a value of given type, but got something else

MathOp(Val, MathOp, Val)

1 - "a"

Index(Val, Val)

{} | .[0] or [] | has("a") or {} | has(0)

IndexOutOfBounds(isize)

[] | .[0] = 0

PathExp

0 |= .+1

TailCall(TailCall)

Tail-recursive call.

This is used internally to execute tail-recursive filters. If this can be observed by users, then this is a bug.

Implementations

impl Error

pub fn as_val(self) -> Val

Convert the error into a value to be used by catch filters.

pub fn str(s: impl ToString) -> Self

Build an error from something that can be converted to a string.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

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 PartialEq for Error

fn eq(&self, other: &Error) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
