Struct Violation 

pub struct Violation {
    pub invariant: Invariant,
    pub path: String,
    pub detail: String,
}

An array the guard will not let through.

The three fields are the three questions somebody debugging this asks in order: which rule, where in the batch, and what the numbers were. A message that answers only the first is the reason people stop reading error messages.

Fields

invariant: Invariant

The rule that was broken.

path: String

Where in the batch, as a dotted path of field names.

detail: String

The numbers, for whoever has to fix the decoder.

Trait Implementations

impl Clone for Violation

fn clone(&self) -> Violation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Violation

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

Formats the value using the given formatter.

impl Display for Violation

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

Formats the value using the given formatter.

impl Eq for Violation

impl Error for Violation

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 Violation

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

Equality operator ==.

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

Inequality operator !=.
