Enum PureFn 

pub enum PureFn {
    Eq,
    Ne,
    Not,
    And,
    Or,
    Concat,
    Len,
    Coalesce,
    JsonPath,
    RegexMatch,
}

The closed pure-function whitelist (spine §7 / A.4, 02 §8.2).

Variants

Eq

(T, T) → boolean

Ne

(T, T) → boolean

Not

(boolean) → boolean

And

(boolean…) → boolean (arity ≥ 2)

Or

(boolean…) → boolean (arity ≥ 2)

Concat

(string…) → string (arity ≥ 1)

Len

(string | array) → number

Coalesce

(T?, …, T) → T — first non-absent value (arity ≥ 2)

JsonPath

(any, string) → any — path must be a literal string

RegexMatch

(string, string[, string]) → boolean — pattern/flags must be literals

Trait Implementations

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PureFn

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for PureFn

impl Hash for PureFn

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl JsonSchema for PureFn

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Ord for PureFn

fn cmp(&self, other: &PureFn) -> 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,

Restrict a value to a certain interval.

impl PartialEq for PureFn

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for PureFn

fn partial_cmp(&self, other: &PureFn) -> 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

impl Serialize for PureFn

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
