Methods

impl ElementSegment

pub fn new(
    index: u32,
    offset: Option<InitExpr>,
    members: Vec<u32>,
    passive: bool
) -> Self

New element segment.

Important traits for &'_ [u8]

impl<'_> Read for &'_ [u8]impl<'_> Write for &'_ mut [u8]

pub fn members(&self) -> &[u32]

Sequence of function indices.

Important traits for Vec<u8>

impl Write for Vec<u8>

pub fn members_mut(&mut self) -> &mut Vec<u32>

Sequence of function indices (mutable)

pub fn index(&self) -> u32

Table index (currently valid only value of 0)

pub fn offset(&self) -> &Option<InitExpr>

An i32 initializer expression that computes the offset at which to place the elements.

Note that this return None if the segment is passive.

pub fn offset_mut(&mut self) -> &mut Option<InitExpr>

An i32 initializer expression that computes the offset at which to place the elements (mutable)

Note that this return None if the segment is passive.

pub fn passive(&self) -> bool

Whether or not this table element is "passive"

pub fn passive_mut(&mut self) -> &mut bool

Whether or not this table element is "passive"
