Struct LexBuffer 

pub struct LexBuffer { /* private fields */ }

Placeholder for LexBuffer from lua_vm::zio. TODO(port): replace with use lua_vm::zio::LexBuffer in Phase B. C: Mbuffer — growable byte buffer for token text. types.tsv: Mbuffer → LexBuffer

Implementations

impl LexBuffer

pub fn new() -> Self

C: luaZ_initbuffer — construct an empty buffer.

pub fn len(&self) -> usize

C: #define luaZ_bufflen(b) ((b)->n) — live byte count. macros.tsv: luaZ_bufflen → buf.len()

pub fn capacity(&self) -> usize

C: #define luaZ_sizebuffer(b) ((b)->buffsize) — allocated capacity. macros.tsv: luaZ_sizebuffer → buf.capacity()

pub fn as_slice(&self) -> &[u8]

C: #define luaZ_buffer(b) ((b)->buffer) — raw byte slice. macros.tsv: luaZ_buffer → buf.as_mut_slice()

pub fn clear(&mut self)

C: #define luaZ_resetbuffer(b) ((b)->n = 0) — reset to zero length. macros.tsv: luaZ_resetbuffer → buf.clear()

pub fn truncate_by(&mut self, i: usize)

C: #define luaZ_buffremove(b, i) ((b)->n -= (i)). macros.tsv: luaZ_buffremove → buf.truncate_by(i)

pub fn resize( &mut self, _state: &mut LuaState, size: usize, ) -> Result<(), LuaError>

C: luaZ_resizebuffer(L, b, newsize) — grow/shrink the buffer’s allocated capacity. In C this changes buffsize, not the live byte count n. The Rust analogue therefore manipulates Vec::capacity, never Vec::len (otherwise push_byte would write past the live content and leave embedded zero padding inside the token text).

Trait Implementations

impl Default for LexBuffer

fn default() -> Self

Returns the “default value” for a type.
