Struct DeclaredParam 

pub struct DeclaredParam {
    pub name: Name,
    pub ty: Option<Arc<Type>>,
    pub out_ty: Option<Arc<Type>>,
    pub has_default: bool,
    pub is_variadic: bool,
    pub is_byref: bool,
    pub is_optional: bool,
}

Fields

name: Name

ty: Option<Arc<Type>>

Parameter type. Stored as Option<Arc<Type>> to enable deduplication of common types across parameters. Many parameters share types like string, int, bool, etc., so interning via Arc saves allocations.

out_ty: Option<Arc<Type>>

Out-type declared via @param-out / @psalm-param-out. When set, this type is written back to the caller’s argument variable after the call instead of (or in addition to) the declared in-type.

has_default: bool

Whether this parameter has a default value. During analysis, defaults are never used for their value — only for marking parameters as optional.

is_variadic: bool

is_byref: bool

is_optional: bool
