Enum rocket_dyn_templates::minijinja::value::ValueKind

#[non_exhaustive]
pub enum ValueKind {
    Undefined,
    None,
    Bool,

}

Describes the kind of value.

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.

Undefined

The value is undefined

None

The value is the none singleton (())

Bool

The value is a bool

Number

The value is a number of a supported type.

String

The value is a string.

Bytes

The value is a byte array.

Seq

The value is an array of other values.

Map

The value is a key/value mapping.

Iterable

An iterable

Plain

A plain object without specific behavior.

Invalid

This value is invalid (holds an error).

This can happen when a serialization error occurred or the engine encountered a failure in a place where an error can otherwise not be produced. Interacting with such values in the context of the template evaluation process will attempt to propagate the error.

Trait Implementations

impl Clone for ValueKind

fn clone(&self) -> ValueKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ValueKind

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

Formats the value using the given formatter.

impl Display for ValueKind

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

Formats the value using the given formatter.

impl Ord for ValueKind

fn cmp(&self, other: &ValueKind) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for ValueKind

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

impl PartialOrd for ValueKind

fn partial_cmp(&self, other: &ValueKind) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
