Enum starlark::ErrorKind

#[non_exhaustive]
pub enum ErrorKind {
    Fail(Error),
    Value(Error),
    Function(Error),
    Scope(Error),
    Lexer(Error),
    Internal(Error),
    Other(Error),
}

The different kinds of errors that can be produced by starlark

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.

Fail(Error)

An explicit fail invocation

Value(Error)

An error approximately associated with a value.

Includes unsupported operations, missing attributes, things of that sort.

Function(Error)

Errors relating to the way a function is called (wrong number of args, etc.)

Scope(Error)

Out of scope variables and similar

Lexer(Error)

Error when lexing a file

Internal(Error)

Indicates a logic bug in starlark

Other(Error)

Fallback option

This is used in two cases:

1. For errors produced by starlark which have not yet been assigned their own kind
2. When a native function invoked as a part of starlark evaluation returns a anyhow::Error

Implementations

impl ErrorKind

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

The source of the error, akin to [std::error::Error::source]

Trait Implementations

impl Debug for ErrorKind

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

Formats the value using the given formatter.

impl Display for ErrorKind

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

Formats the value using the given formatter.
