Enum arithmetic_typing::error::ErrorPathFragment

#[non_exhaustive]
pub enum ErrorPathFragment {
    FnArg(Option<TupleIndex>),
    FnReturnType,
    TupleElement(Option<TupleIndex>),
    ObjectField(String),
    Lhs,
    Rhs,
}

Fragment of a path for an Error.

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.

FnArg(Option<TupleIndex>)

Function argument with the specified index (0-based; can be None if the error cannot be attributed to a specific index).

FnReturnType

Function return type.

TupleElement(Option<TupleIndex>)

Tuple element with the specified index (0-based; can be None if the error cannot be attributed to a specific index).

ObjectField(String)

Object field with the specified name.

Lhs

Left-hand side of a binary operation.

Rhs

Right-hand side of a binary operation.

Trait Implementations

impl Clone for ErrorPathFragment

fn clone(&self) -> ErrorPathFragment

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorPathFragment

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

Formats the value using the given formatter.

impl From<&str> for ErrorPathFragment

fn from(field_name: &str) -> Self

Converts to this type from the input type.

impl From<TupleIndex> for ErrorPathFragment

fn from(index: TupleIndex) -> Self

Converts to this type from the input type.

impl PartialEq for ErrorPathFragment

fn eq(&self, other: &ErrorPathFragment) -> 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.
