Implementations

impl Attribute

pub fn new(name: String, required: bool) -> Self

Creates a new Attribute with the given name and required status.

Arguments

• name - The name of the attribute.
• required - Indicates if the attribute is required.

pub fn set_docstring(&mut self, docstring: String)

Sets the documentation string for the attribute.

Arguments

• docstring - The documentation string to set.

pub fn set_position(&mut self, position: Position)

Sets the line number of the attribute.

Arguments

• position - The position to set.

pub fn add_option(&mut self, option: RawOption) -> Result<(), Box<dyn Error>>

Adds an option to the attribute.

Arguments

• option - The option to add.

pub fn to_json_schema(&self) -> String

Converts the attribute to a JSON schema.

Returns

A JSON string representing the attribute schema.

pub fn has_term(&self) -> bool

Checks if the attribute has an associated term.

Returns

true if the attribute has a term, false otherwise.

pub fn set_xml(&mut self, xml: XMLType)

Sets the XML type for the attribute.

Arguments

• xml - The XML type to set.

Trait Implementations

impl Clone for Attribute

fn clone(&self) -> Attribute

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Attribute

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

Formats the value using the given formatter.

impl Default for Attribute

fn default() -> Attribute

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Attribute

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&Attribute> for Option<Item>

Specific case for the items field in the JSON schema.

fn from(attr: &Attribute) -> Self

Converts an Attribute into an Option<Item>.

Arguments

• attr - A reference to the Attribute.

Returns

An Option<Item> representing the attribute’s items.

impl From<&Attribute> for Vec<Item>

fn from(attr: &Attribute) -> Self

Converts an Attribute into a Vec<Item>.

Arguments

• attr - A reference to the Attribute.

Returns

A Vec<Item> representing the attribute’s items.

impl From<Attribute> for AttributeDefinition

Implements conversion from Attribute to LinkML AttributeDefinition.

fn from(attribute: Attribute) -> Self

Converts an Attribute into a LinkML AttributeDefinition.

This conversion preserves:

• Array/multivalued status
• Data type (range)
• Documentation
• ID status
• Required status
• Minimum and maximum values
• Examples
• Term mappings

impl From<AttributeDefinition> for Attribute

Implements conversion from LinkML AttributeDefinition to Attribute.

fn from(attr: AttributeDefinition) -> Self

Converts a LinkML AttributeDefinition into an internal Attribute representation.

This conversion preserves:

• Documentation
• Data type/range
• Cardinality (multivalued status)
• Identifier status
• Required status
• URI/term mapping

Arguments

• attr - The LinkML AttributeDefinition to convert

Returns

An Attribute representing the slot in the internal model format

impl PartialEq for Attribute

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&Attribute> for DataType

fn try_from(attr: &Attribute) -> Result<Self, Self::Error>

Attempts to convert an Attribute into a DataType.

Arguments

• attr - A reference to the Attribute.

Returns

A Result containing the DataType or an error message.

Errors

Returns an error if the dtypes vector in the attribute is empty.

type Error = String

The type returned in the event of a conversion error.

impl TryFrom<&Attribute> for Property

fn try_from(attr: &Attribute) -> Result<Self, Self::Error>

Attempts to convert an Attribute into a Property.

Arguments

• attr - A reference to the Attribute.

Returns

A Result containing the Property or an error message.

type Error = String

The type returned in the event of a conversion error.

impl TryFrom<Property> for Attribute

Converts a JSON Schema property to an Attribute

This implementation handles various property types including:

• Array properties with items
• Properties with direct data types
• Properties with references
• Properties with oneOf (multiple possible types)

type Error = Box<dyn Error>

The type returned in the event of a conversion error.

fn try_from(property: Property) -> Result<Self, Self::Error>

Performs the conversion.
