Enum rtlola_frontend::mir::ExpressionKind [−][src]
pub enum ExpressionKind { LoadConstant(Constant), ArithLog(ArithLogOp, Vec<Expression>), StreamAccess { target: StreamReference, parameters: Vec<Expression>, access_kind: StreamAccessKind, }, ParameterAccess(StreamReference, usize), Ite { condition: Box<Expression>, consequence: Box<Expression>, alternative: Box<Expression>, }, Tuple(Vec<Expression>), TupleAccess(Box<Expression>, usize), Function(String, Vec<Expression>), Convert { expr: Box<Expression>, }, Default { expr: Box<Expression>, default: Box<Expression>, }, }
Expand description
This enum contains all possible kinds of expressions and their relevant information.
Variants
LoadConstant(Constant)
Load a constant value
ArithLog(ArithLogOp, Vec<Expression>)
Apply an arithmetic or logic operation. The function is monomorphized.
Note: Arguments never need to be coerced. Unary: 1st argument -> operand Binary: 1st argument -> lhs, 2nd argument -> rhs n-ary: kth argument -> kth operand
Access another stream
Show fields
Fields of StreamAccess
target: StreamReference
The target stream to be accessed
parameters: Vec<Expression>
The parameters of the specific stream instance that is accessed.
If the stream behind target
is not parametrized, this collection is empty.
access_kind: StreamAccessKind
The kind of access
ParameterAccess(StreamReference, usize)
Access to the parameter of a stream represented by a stream reference, referencing the target stream and the index of the parameter that should be accessed.
A conditional (if-then-else) expression
Show fields
Fields of Ite
condition: Box<Expression>
The condition under which either consequence
or alternative
is selected.
consequence: Box<Expression>
The consequence should be evaluated and returned if the condition evaluates to true.
alternative: Box<Expression>
The alternative should be evaluated and returned if the condition evaluates to false.
Tuple(Vec<Expression>)
A tuple expression
TupleAccess(Box<Expression>, usize)
Represents a tuple projections, i.e., it accesses a specific tuple element.
Function(String, Vec<Expression>)
Represents a function call. The function is monomorphized.
Note: Arguments never need to be coerced. Unary: 1st argument -> operand Binary: 1st argument -> lhs, 2nd argument -> rhs n-ary: kth argument -> kth operand
Converting a value to a different type
The result type is indicated in the expression with the Convert
kind.
Show fields
Fields of Convert
expr: Box<Expression>
The expression that produces a value. The type of the expression indicates the source of the conversion.
Transforms an optional value into a definitive one
Show fields
Fields of Default
expr: Box<Expression>
The expression that results in an optional value.
default: Box<Expression>
An infallible expression providing the default value if expr
fails to produce a value.
