Fields

name: String

Attribute name (e.g., name from has 'name' => (...))

is: Option<AccessorType>

Accessor mode

isa: Option<String>

Type constraint string (e.g., Str, ArrayRef[Int])

default: bool

Whether a default value is specified

required: bool

Whether required => 1 is set

accessor_name: String

Name of the accessor method (may differ from attribute name)

location: ByteSpan
