Struct cranelift_codegen::ir::entities::Immediate

[+] Show declaration

pub struct Immediate(_);

[−] Expand description

An opaque reference to an immediate.

Some immediates (e.g. SIMD shuffle masks) are too large to store in the InstructionData struct and therefore must be tracked separately in DataFlowGraph::immediates. Immediate provides a way to reference values stored there.

While the order is stable, it is arbitrary.

Implementations

impl Immediate[−]

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.

impl Immediate[−]

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

Create an immediate reference from its number.

This method is for use by the parser.

Trait Implementations

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

Formats the value using the given formatter.

impl Display for Immediate[+]

[+] Show hidden undocumented items

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

Formats the value using the given formatter.

impl EntityRef for Immediate[+]

[+] Show hidden undocumented items

fn new(index: usize) -> Self[−]

impl Eq for Immediate

impl Hash for Immediate[+]

[+] Show hidden undocumented items

fn hash<__H: Hasher>(&self, state: &mut __H)[−]

Feeds this value into the given Hasher.

pub fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, [−]

Feeds a slice of this type into the given Hasher.

impl Ord for Immediate[+]
