Type Alias VarDefine

pub type VarDefine = VarDefine<Undeclared<Value>>;

Aliased Type

pub struct VarDefine {
    pub ty: GroupIdx,
    pub name: String,
    pub init: Option<Undeclared<AssignValue>>,
    pub is_temp: bool,
}

Fields

ty: GroupIdx

the type of the variable

name: String

the name of the variable, either a named variable or a temp variable from computing

init: Option<Undeclared<AssignValue>>

the initial value of the variable

[None] represents the variable is not initialized when it was created

is_temp: bool

a temp value will only be immediately used once in expressions

this is a hint for code generation backend optimization

code generation backend can directly inline init only when is_temp is true
