Struct libfirm_rs::nodes::Switch

pub struct Switch(_);

Change control flow. The destination is chosen based on an integer input value which is looked up in a table.

Backends can implement this efficiently using a jump table.

Methods

impl Switch

pub fn selector(self) -> Node

Gets input selector.

pub fn set_selector(     self,     val: impl NodeTrait )

Sets input selector.

pub fn n_outs(self) -> c_uint

Gets number of outputs (including pn_Switch_default).

pub fn set_n_outs(self, val: c_uint)

Sets number of outputs (including pn_Switch_default).

pub fn table(self) -> *mut ir_switch_table

Gets table describing mapping from input values to Proj numbers.

pub fn set_table(self, val: *mut ir_switch_table)

Sets table describing mapping from input values to Proj numbers.

pub fn new_proj_default(self, mode: Mode) -> Proj

control flow if no other case matches.

pub fn out_proj_default(self) -> Option<Proj>

control flow if no other case matches.

Trait Implementations

fn out_nodes_ex(&self) -> OutNodeExIterator

fn all_out_projs(&self) -> Vec<Proj>

fn collect_all_out_projs(&self, projs: &mut Vec<Proj>)

Important traits for InNodeIterator

impl Iterator for InNodeIterator type Item = Node;

fn in_nodes(&self) -> InNodeIterator

fn set_input_at(&self, idx: i32, pred: Node)

fn set_in_nodes(&self, nodes: &[Node])

fn node_id(&self) -> i64

fn is_pinned(&self) -> bool

fn is_commutative(&self) -> bool

fn is_only_valid_in_start_block(&self) -> bool

fn graph(&self) -> Graph

fn walk<F>(&self, walker: F) where     F: FnMut(VisitTime, Node),     Self: Sized,

libifrm irg_walk wrapper

fn walk_dfs_in_block_stop_at_phi_node<Callback>(     &self,     block: Block,     callback: &mut Callback ) where     Callback: FnMut(Node),     Self: Sized,

Perform a DFS over all nodes within block starting at self. As soon as a Phi node is reached, that branch of the DFS is canceled. There is no callback for a Phi node. The primary use case for this API is in codegen.

impl NodeDebug for Switch

fn fmt(&self, f: &mut Formatter, _opts: NodeDebugOpts) -> Result

fn debug_fmt(self) -> NodeDebugFmt<Self> where     Self: Sized + Copy,

impl PartialEq<Switch> for Switch

fn eq(&self, other: &Switch) -> bool

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

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

This method tests for !=.

impl From<Switch> for Node

fn from(node: Switch) -> Node

Performs the conversion.

impl Clone for Switch

fn clone(&self) -> Switch

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Switch

impl Eq for Switch

impl Debug for Switch

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

Formats the value using the given formatter.

impl Hash for Switch

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].
