Enum ExtensionRelationType 

pub enum ExtensionRelationType {
    Leaf,
    Single,
    Multi,
}

Extension relation types

Variants

Leaf

Extension leaf relation - no input children

Single

Extension single relation - exactly one input child

Multi

Extension multi relation - zero or more input children

Implementations

impl ExtensionRelationType

pub fn as_str(&self) -> &'static str

Get the string representation used in the text format

pub fn validate_child_count(&self, child_count: usize) -> Result<(), String>

Validate that the child count matches this relation type

impl ExtensionRelationType

pub fn create_rel( self, detail: Option<Any>, children: Vec<Box<Rel>>, ) -> Result<Rel, String>

Create appropriate relation structure from extension detail and children. This method handles the structural logic for creating different extension relation types.

Trait Implementations

impl Clone for ExtensionRelationType

fn clone(&self) -> ExtensionRelationType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExtensionRelationType

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

Formats the value using the given formatter.

impl FromStr for ExtensionRelationType

type Err = String

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for ExtensionRelationType

fn eq(&self, other: &ExtensionRelationType) -> 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.
