Enum ScalarError 

pub enum ScalarError {
    Kind {
        raw: String,
        wanted: &'static str,
    },
    Choice {
        raw: String,
        allowed: Vec<String>,
    },
    Rule {
        raw: String,
        rule: String,
    },
    Pattern {
        pattern: String,
        message: String,
    },
}

A raw argument the document’s schema rejects.

Variants

Kind

Not the kind of value the document asks for at all.

Fields

raw: String

wanted: &'static str

Choice

Outside the document’s enum — the one refusal that can say what to type instead, which is why it carries the list rather than a sentence.

Fields

raw: String

allowed: Vec<String>

Rule

The right kind of value, refused by a rule the document states. rule finishes the sentence and carries the document’s own number, which is the only part a user can act on; nothing branches on which keyword it came from.

Fields

raw: String

rule: String

Pattern

A pattern the engine cannot read. Every value is refused, because a rule nobody can run is not a rule everything passed — and a document stating one is refused outright while it is reduced.

Fields

pattern: String

message: String

Trait Implementations

impl Clone for ScalarError

fn clone(&self) -> ScalarError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScalarError

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

Formats the value using the given formatter.

impl Display for ScalarError

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

Formats the value using the given formatter.

impl Eq for ScalarError

impl Error for ScalarError

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 ScalarError

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

Equality operator ==.

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

Inequality operator !=.
