CodeValue

Struct CodeValue

#[repr(C)]pub struct CodeValue {
    pub tag: u8,
    pub number: f64,
    pub string: *const c_char,
    pub boolean: u8,
    pub fields: *const CodeField,
    pub field_count: u32,
    pub elements: *const CodeValue,
    pub element_count: u32,
}

Expand description

A single Code value in C-ABI representation.

Active fields depend on tag:

CODE_TAG_NUMBER → number
CODE_TAG_STRING → string (null-terminated UTF-8 C string)
CODE_TAG_BOOLEAN → boolean (0 = false, non-zero = true)
CODE_TAG_OBJECT → fields + field_count
CODE_TAG_NULL → (no data)
CODE_TAG_ARRAY → elements + element_count
