Variants

Var(String)

Variable reference.

IntLit(i64)

Integer literal.

UIntLit(u64)

Unsigned integer literal.

StringLit(String)

String literal.

Call(String, Vec<CExpr>)

Function call: f(args...).

BinOp(CBinOp, Box<CExpr>, Box<CExpr>)

Binary operation: lhs op rhs.

UnaryOp(CUnaryOp, Box<CExpr>)

Unary operation: op expr.

FieldAccess(Box<CExpr>, String, bool)

Field access: expr.field or expr->field.

ArrayAccess(Box<CExpr>, Box<CExpr>)

Array access: expr[index].

Cast(CType, Box<CExpr>)

Cast: (type)expr.

SizeOf(CType)

sizeof(type).

Null

Trait Implementations

impl Clone for CExpr

fn clone(&self) -> CExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CExpr

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

Formats the value using the given formatter.

impl Display for CExpr

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

Formats the value using the given formatter.

impl PartialEq for CExpr

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
