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>) -> 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.

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

Initial value of the data segment.

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

Initial value of the data segment (mutable).

impl Clone for DataSegment

fn clone(&self) -> DataSegment

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)
