Enum TargetRefError 

#[non_exhaustive]
pub enum TargetRefError {
    InvalidValue {
        field: &'static str,
        max_chars: usize,
    },
    ExcessiveDepth {
        max_depth: usize,
    },
}

Validation failure for a target reference.

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.

InvalidValue

A textual target field was empty, oversized, or contained control characters.

Fields

field: &'static str

Target field.

max_chars: usize

Maximum accepted character count.

ExcessiveDepth

The parent chain exceeded the defensive recursion bound.

Fields

max_depth: usize

Maximum parent depth.

Trait Implementations

impl Clone for TargetRefError

fn clone(&self) -> TargetRefError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TargetRefError

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

Formats the value using the given formatter.

impl Display for TargetRefError

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

Formats the value using the given formatter.

impl Error for TargetRefError

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 PartialEq for TargetRefError

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