Enum ControlFlowKind 

pub enum ControlFlowKind {
    BreakOnly,
    BreakOrReturn,
}

This is a marker to describe what control flow is present in a loop. It is added by phase DropReturnBreakContinue and the information is used in FunctionalizeLoops. We need it to replace the control flow nodes of the AST by an encoding in the ControlFlow enum.

Variants

BreakOnly

Contains no return, maybe some breaks

BreakOrReturn

Contains both at least one return and maybe some breaks

Trait Implementations

impl AstVisitable for ControlFlowKind

fn drive_map<V: AstVisitorMut>(&mut self, v: &mut V)

Recursively visit this type with the provided visitor. This calls the visitor’s visit_$any method if it exists, otherwise visit_inner.

fn drive<V: AstVisitor>(&self, v: &mut V)

Recursively visit this type with the provided visitor. This calls the visitor’s visit_$any method if it exists, otherwise visit_inner.

impl AstVisitable for ControlFlowKind

fn drive<V: AstEarlyExitVisitor>(&self, v: &mut V) -> ControlFlow<V::Break>

Recursively visit this type with the provided visitor. This calls the visitor’s visit_$any method if it exists, otherwise visit_inner.

fn drive_mut<V: AstEarlyExitVisitorMut>( &mut self, v: &mut V, ) -> ControlFlow<V::Break>

Recursively visit this type with the provided visitor. This calls the visitor’s visit_$any method if it exists, otherwise visit_inner.

fn clone(&self) -> ControlFlowKind

Returns a duplicate of the value.

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

impl<'de> Deserialize<'de> for ControlFlowKind

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'s, V> Drive<'s, V> for ControlFlowKind

where V: Visitor,

fn drive_inner(&'s self, visitor: &mut V) -> ControlFlow<V::Break>

Call v.visit() on the immediate contents of self.

impl<'s, V> DriveMut<'s, V> for ControlFlowKind

where V: Visitor,

fn drive_inner_mut(&'s mut self, visitor: &mut V) -> ControlFlow<V::Break>

Call v.visit() on the immediate contents of self.

impl<'lt> From<&'lt ControlFlowKind> for FragmentRef<'lt>

fn from(fragment: &'lt ControlFlowKind) -> Self

Converts to this type from the input type.

impl From<ControlFlowKind> for Fragment

fn from(fragment: ControlFlowKind) -> Self

Converts to this type from the input type.

impl Hash for ControlFlowKind

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 JsonSchema for ControlFlowKind

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl Ord for ControlFlowKind

fn cmp(&self, other: &ControlFlowKind) -> 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 PartialEq for ControlFlowKind

fn eq(&self, other: &ControlFlowKind) -> 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 PartialOrd for ControlFlowKind

fn partial_cmp(&self, other: &ControlFlowKind) -> 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.

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.
