Sentinel type used during type inference to represent “type could not be determined.” This propagates through expressions without generating cascading errors. It must never appear in a successfully validated graph or execution plan.

Implementations

impl TypeSpecification

pub fn boolean() -> Self

pub fn scale() -> Self

pub fn number() -> Self

pub fn ratio() -> Self

pub fn text() -> Self

pub fn date() -> Self

pub fn time() -> Self

pub fn duration() -> Self

pub fn veto() -> Self

pub fn apply_constraint( self, command: &str, args: &[CommandArg], ) -> Result<Self, String>

Trait Implementations

impl Clone for TypeSpecification

fn clone(&self) -> TypeSpecification

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TypeSpecification

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TypeSpecification

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for TypeSpecification

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 TypeSpecification

fn eq(&self, other: &TypeSpecification) -> 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 Serialize for TypeSpecification

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 TypeSpecification

impl StructuralPartialEq for TypeSpecification
