Enum Function

#[non_exhaustive]
pub enum Function {
    Normal(String, Vec<Value>),
    Custom(String, Vec<Value>),
    Script(Script, Vec<Value>),
    Anonymous(Value, Vec<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.

Normal(String, Vec<Value>)

Custom(String, Vec<Value>)

Script(Script, Vec<Value>)

Anonymous(Value, Vec<Value>)

Trait Implementations

impl Clone for Function

fn clone(&self) -> Function

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Function

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Function

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Function

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

Formats the value using the given formatter.

impl From<Function> for Query

fn from(f: Function) -> Self

Converts to this type from the input type.

impl From<Function> for Value

fn from(v: Function) -> Self

Converts to this type from the input type.

impl Hash for Function

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,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Function

fn eq(&self, other: &Function) -> 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 Function

fn partial_cmp(&self, _: &Self) -> 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.

impl Revisioned for Function

fn revision() -> u16

Returns the current revision of this type.

fn serialize_revisioned<W: Write>(&self, writer: &mut W) -> Result<(), Error>

Serializes the struct using the specficifed writer.

fn deserialize_revisioned<R: Read>(reader: &mut R) -> Result<Self, Error>

Deserializes a new instance of the struct from the specficifed reader.

fn type_id() -> TypeId

where Self: 'static,

Returns the type id of this type.

impl Serialize for Function

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Function

impl StructuralPartialEq for Function
