terminator: Terminator

Implementations

impl BlockData

pub fn new_goto(span: Span, target: BlockId) -> Self

Build a block that’s just a goto terminator.

pub fn targets(&self) -> Vec<BlockId>

pub fn transform_operands<F: FnMut(&Span, &mut Vec<Statement>, &mut Operand)>( &mut self, f: F, )

TODO: Write new documentation

pub fn transform<F: FnMut(&mut Statement) -> Vec<Statement>>(&mut self, f: F)

Apply a transformer to all the statements.

The transformer should:

• mutate the current statement in place
• return the sequence of statements to introduce before the current statement

fn transform_sequences<F>(&mut self, f: F, forward: bool)

where F: FnMut(&mut [Statement]) -> Vec<(usize, Vec<Statement>)>,

Helper, see transform_sequences_fwd and transform_sequences_bwd.

pub fn transform_sequences_fwd<F>(&mut self, f: F)

where F: FnMut(&mut [Statement]) -> Vec<(usize, Vec<Statement>)>,

Apply a transformer to all the statements.

The transformer should:

• mutate the current statements in place
• return a list of (i, statements) where statements will be inserted before index i.

pub fn transform_sequences_bwd<F>(&mut self, f: F)

where F: FnMut(&mut [Statement]) -> Vec<(usize, Vec<Statement>)>,

Apply a transformer to all the statements.

The transformer should:

• mutate the current statements in place
• return a list of (i, statements) where statements will be inserted before index i.

Trait Implementations

impl AstVisitable for BlockData

fn drive<V: VisitAst>(&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: VisitAstMut>(&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 name(&self) -> &'static str

The name of the type, used for debug logging.

fn dyn_visit<T: AstVisitable>(&self, f: impl FnMut(&T))

Visit all occurrences of that type inside self, in pre-order traversal.

fn dyn_visit_mut<T: AstVisitable>(&mut self, f: impl FnMut(&mut T))

Visit all occurrences of that type inside self, in pre-order traversal.

impl BodyVisitable for BlockData

fn drive_body<V: VisitBody>(&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_body_mut<V: VisitBodyMut>( &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 dyn_visit_in_body<T: BodyVisitable>(&self, f: impl FnMut(&T))

Visit all occurrences of that type inside self, in pre-order traversal.

fn dyn_visit_in_body_mut<T: BodyVisitable>(&mut self, f: impl FnMut(&mut T))

Visit all occurrences of that type inside self, in pre-order traversal.

impl Clone for BlockData

fn clone(&self) -> BlockData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockData

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BlockData

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 BlockData

where V: Visitor + Visit<'s, Vec<Statement>> + Visit<'s, Terminator>,

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 BlockData

where V: Visitor + VisitMut<'s, Vec<Statement>> + VisitMut<'s, Terminator>,

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

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

impl<C: AstFormatter> FmtWithCtx<C> for BlockData

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

fn with_ctx<'a>(&'a self, ctx: &'a C) -> WithCtx<'a, C, Self>

Returns a struct that implements Display. This allows the following:

fn to_string_with_ctx(&self, ctx: &C) -> String

impl Serialize for BlockData

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

where __S: Serializer,
