Struct AccessError

pub struct AccessError<'a> { /* private fields */ }

An error originating from an Access of an element within a type.

Use the Display impl of this type to get information on the error.

Some sample messages:

Error accessing element with `.alpha` access (offset 14): The struct accessed doesn't have an "alpha" field
Error accessing element with '[0]' access: Expected index access to access a list, found a struct instead.
Error accessing element with '.4' access: Expected variant index access to access a Tuple variant, found a Unit variant instead.

Implementations

impl<'a> AccessError<'a>

pub const fn kind(&self) -> &AccessErrorKind

Returns the kind of AccessError.

pub const fn access(&self) -> &Access<'_>

The returns the Access that this AccessError occurred in.

pub const fn offset(&self) -> Option<&usize>

If the Access was created with a parser or an offset was manually provided, returns the offset of the Access in its path string.

Trait Implementations

impl<'a> Clone for AccessError<'a>

fn clone(&self) -> AccessError<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for AccessError<'a>

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

Formats the value using the given formatter.

impl Display for AccessError<'_>

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

Formats the value using the given formatter.

impl Error for AccessError<'_>

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<'a> From<AccessError<'a>> for ReflectPathError<'a>

fn from(value: AccessError<'a>) -> Self

Converts to this type from the input type.

impl<'a> PartialEq for AccessError<'a>

fn eq(&self, other: &AccessError<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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