Struct EdgeStmt

pub struct EdgeStmt<A> {
    pub from: Either<NodeID, Subgraph<A>>,
    pub next: EdgeRHS<A>,
    pub attr: Option<AttrList<A>>,
}

The description of an edge. This corresponds to the edge_stmt non-terminal of the grammar.

Fields

from: Either<NodeID, Subgraph<A>>

The origin of the edge.

next: EdgeRHS<A>

The destination of the edge.

attr: Option<AttrList<A>>

The attributes of the edge.

Implementations

impl<'a, A> EdgeStmt<A>

pub fn flatten(self) -> Vec<EdgeStmt<A>>

where A: Clone,

Flatten the EdgeStmt, i.e. removes cases where multiple EdgeRHS are in a single statement.

Trait Implementations

impl<A: Clone> Clone for EdgeStmt<A>

fn clone(&self) -> EdgeStmt<A>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<A: Debug> Debug for EdgeStmt<A>

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

Formats the value using the given formatter.

impl<A> From<EdgeStmt<A>> for Vec<EdgeStmt<A>>

where A: Clone,

fn from(edge: EdgeStmt<A>) -> Vec<EdgeStmt<A>>

Converts to this type from the input type.

impl<A: Hash> Hash for EdgeStmt<A>

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<A: Ord> Ord for EdgeStmt<A>

fn cmp(&self, other: &EdgeStmt<A>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<A: PartialEq> PartialEq for EdgeStmt<A>

fn eq(&self, other: &EdgeStmt<A>) -> 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<A: PartialOrd> PartialOrd for EdgeStmt<A>

fn partial_cmp(&self, other: &EdgeStmt<A>) -> 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<'a, A> TryFrom<Pair<'a, Rule>> for EdgeStmt<A>

where AList<A>: TryFrom<Pair<'a, Rule>, Error = ParseError<'a>>,

type Error = ParseError<'a>

The type returned in the event of a conversion error.

fn try_from(p: Pair<'a, Rule>) -> Result<Self, ParseError<'a>>

Performs the conversion.
