Struct TableFlags 

pub struct TableFlags(pub u8);

Bitfield for a LuaTable: lower bits record absent fast-access metamethods; bit 7 encodes whether alimit is the real array size.

Tuple Fields

0: u8

Implementations

impl TableFlags

pub fn is_real_asize(self) -> bool

isrealasize(t) — bit 7 clear means alimit IS the real array size.

pub fn set_real_asize(&mut self)

setrealasize(t) — clear bit 7 so alimit becomes the canonical size.

pub fn set_no_real_asize(&mut self)

setnorealasize(t) — set bit 7 so alimit is only a hint.

pub fn invalidate_tm_cache(&mut self)

invalidateTMcache(t) — clear all fast-access metamethod bits.
