Enum dot_parser::ast::Stmt

pub enum Stmt<'a, A = (&'a str, &'a str)> {
    NodeStmt(NodeStmt<'a, A>),
    EdgeStmt(EdgeStmt<'a, A>),

Variants

NodeStmt(NodeStmt<'a, A>)

EdgeStmt(EdgeStmt<'a, A>)

An edge statement.

AttrStmt(AttrStmt<'a, A>)

An attribute statement.

IDEq(&'a str, &'a str)

An alias statement.

Trait Implementations

impl<'a, A: Debug> Debug for Stmt<'a, A>

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

Formats the value using the given formatter.

impl<'a, A> FromIterator<Stmt<'a, A>> for StmtList<'a, A>

fn from_iter<T>(iter: T) -> Selfwhere
    T: IntoIterator<Item = Stmt<'a, A>>,

Creates a value from an iterator.

impl<'a, A: Hash> Hash for Stmt<'a, 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,

Feeds a slice of this type into the given Hasher.

impl<'a, A: Ord> Ord for Stmt<'a, A>

fn cmp(&self, other: &Stmt<'a, A>) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl<'a, A: PartialEq> PartialEq<Stmt<'a, A>> for Stmt<'a, A>

fn eq(&self, other: &Stmt<'a, A>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a, A: PartialOrd> PartialOrd<Stmt<'a, A>> for Stmt<'a, A>

fn partial_cmp(&self, other: &Stmt<'a, A>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
