Struct cranelift_codegen::ir::entities::Block

pub struct Block(/* private fields */);

An opaque reference to a basic block in a Function.

You can get a Block using FunctionBuilder::create_block

While the order is stable, it is arbitrary and does not necessarily resemble the layout order.

Implementations

impl Block

pub fn from_u32(x: u32) -> Self

Create a new instance from a u32.

pub fn as_u32(self) -> u32

Return the underlying index value as a u32.

pub fn as_bits(self) -> u32

Return the raw bit encoding for this instance.

pub fn from_bits(x: u32) -> Self

Create a new instance from the raw bit encoding.

impl Block

pub fn with_number(n: u32) -> Option<Self>

Create a new block reference from its number. This corresponds to the blockNN representation.

This method is for use by the parser.

Trait Implementations

impl Clone for Block

fn clone(&self) -> Block

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Block

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

Formats the value using the given formatter.

impl Display for Block

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

Formats the value using the given formatter.

impl EntityRef for Block

fn new(index: usize) -> Self

Create a new entity reference from a small integer. This should crash if the requested index is not representable.

fn index(self) -> usize

Get the index that was used to create this entity reference.

impl From<Block> for AnyEntity

fn from(r: Block) -> Self

Converts to this type from the input type.

impl From<Block> for ProgramPoint

fn from(block: Block) -> Self

Converts to this type from the input type.

impl Hash for Block

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 Index<Block> for Blocks

type Output = BlockData

The returned type after indexing.

fn index(&self, block: Block) -> &BlockData

Performs the indexing (container[index]) operation.

impl IndexMut<Block> for Blocks

fn index_mut(&mut self, block: Block) -> &mut BlockData

Performs the mutable indexing (container[index]) operation.

impl Ord for Block

fn cmp(&self, other: &Block) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl PartialEq<Block> for Block

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

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

impl ReservedValue for Block

fn reserved_value() -> Block

Create an instance of the reserved value.

fn is_reserved_value(&self) -> bool

Checks whether value is the reserved one.

impl Copy for Block

impl Eq for Block

impl StructuralEq for Block
