Enum RecipeError 

#[non_exhaustive]
pub enum RecipeError {
    UnknownTemplate {
        template: String,
    },
    UnknownRole {
        role: String,
        known: Vec<&'static str>,
    },
    Family {
        template: String,
        family: &'static str,
        role: &'static str,
        takes: &'static str,
    },
}

Why a template could not take the place a recipe builder gave it.

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.

UnknownTemplate

The code names no registered template.

Fields

template: String

The code as given.

UnknownRole

The spelling names no segment role.

Fields

role: String

The spelling as given.

known: Vec<&'static str>

The roles there are.

Family

The template is of a family the role does not build from.

Fields

template: String

The code as given.

family: &'static str

The family the registry holds it under.

role: &'static str

The role, with the family it takes.

takes: &'static str

The family the role takes.

Trait Implementations

impl Clone for RecipeError

fn clone(&self) -> RecipeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RecipeError

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

Formats the value using the given formatter.

impl Display for RecipeError

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

Formats the value using the given formatter.

impl Eq for RecipeError

impl Error for RecipeError

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 RecipeError

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