Struct cranelift_codegen::ir::pcc::Expr

pub struct Expr {
    pub base: BaseExpr,
    pub offset: i64,
}

A bound expression.

Fields

base: BaseExpr

The dynamic (base) part.

offset: i64

The static (offset) part.

Implementations

impl Expr

pub fn constant(offset: i64) -> Self

Constant value.

pub fn value(value: Value) -> Self

The value of an SSA value.

pub fn global_value(gv: GlobalValue) -> Self

The value of a global value.

pub fn offset(lhs: &Expr, rhs: i64) -> Option<Expr>

Add a static offset to an expression.

pub fn without_offset(&self) -> Option<&BaseExpr>

Is this Expr a BaseExpr with no offset? Return it if so.

Trait Implementations

impl Clone for Expr

fn clone(&self) -> Expr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Expr

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

Formats the value using the given formatter.

impl Display for Expr

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

Formats the value using the given formatter.

impl Hash for Expr

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 PartialEq for Expr

fn eq(&self, other: &Expr) -> 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.
