Struct parity_wasm::elements::DataSegment

pub struct DataSegment { /* fields omitted */ }

Data segment definition.

Methods

impl DataSegment

pub fn new(
    index: u32,
    offset: Option<InitExpr>,
    value: Vec<u8>,
    passive: bool
) -> Self

New data segments.

pub fn index(&self) -> u32

Linear memory index (currently the only valid value is 0).

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

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

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 data (mutable)

Note that this return None if the segment is passive.

Important traits for &'_ [u8]

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

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

Initial value of the data segment.

Important traits for Vec<u8>

impl Write for Vec<u8>

pub fn value_mut(&mut self) -> &mut Vec<u8>

Initial value of the data segment (mutable).

pub fn passive(&self) -> bool

Whether or not this data segment is "passive".

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

Whether or not this data segment is "passive" (mutable).
