Struct InternedType 

Source 
pub struct InternedType(/* private fields */);
Expand description

Interned type index - 32 bits, Copy, cheap comparison.

Reserved indices 0-15 are primitives (no lookup needed). Index 16+ are composite types stored in the pool.

§Primitive Encoding

The following indices are reserved for primitive types:

  • 0: i8
  • 1: i16
  • 2: i32
  • 3: i64
  • 4: u8
  • 5: u16
  • 6: u32
  • 7: u64
  • 8: isize
  • 9: usize
  • 10: f16
  • 11: f32
  • 12: f64
  • 13: bool
  • 14: unit
  • 15: never
  • 16: error
  • 17-18: reserved for future primitives

Source

pub fn is_primitive(self) -> bool

Check if this is a primitive type (no pool lookup needed).

Source

pub fn index(self) -> u32

Get the raw index value.

Source

pub fn from_raw(index: u32) -> Self

Create an InternedType from a raw index.

§Safety

The caller must ensure the index is valid (either a primitive index 0-15, or a composite index that exists in the pool).

Source

pub fn pool_index(self) -> Option<u32>

Get the pool index for a composite type.

Returns None for primitive types.
