Struct Element 

pub struct Element<Identifier = String> {
    pub info: MetaInfo<Identifier>,
    pub list: OffsetList<Identifier>,
    pub index: Option<IntExp<Identifier>>,
    pub value: Option<IntExp<Identifier>>,
    pub condition: Option<Condition<Identifier>>,
}

Constraint that enforces that the value of the expression at Self::index abides by the given Self::condition, or alternatively is equal the expression Self::value.

Fields

info: MetaInfo<Identifier>

Optional metadata for the constraint

list: OffsetList<Identifier>

Indexed list of values

index: Option<IntExp<Identifier>>

Index of the value to be constrained

value: Option<IntExp<Identifier>>

Value to be assigned to the indexed expression

condition: Option<Condition<Identifier>>

Condition to be enforced on the indexed expression

Trait Implementations

impl<Identifier: Clone> Clone for Element<Identifier>

fn clone(&self) -> Element<Identifier>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Identifier: Debug> Debug for Element<Identifier>

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

Formats the value using the given formatter.

impl<'de, Identifier> Deserialize<'de> for Element<Identifier>

where Identifier: FromStr,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<Identifier: Hash> Hash for Element<Identifier>

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<Identifier: PartialEq> PartialEq for Element<Identifier>

fn eq(&self, other: &Element<Identifier>) -> 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<Identifier> Serialize for Element<Identifier>

where Identifier: Display,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
