Expand description

A data segment.

Every data segment has an associated value. This value gets copied into a memory. It is either automatically copied into a specific memory at Wasm instantiation time (active data segments) or dynamically copied into a memory (or memories) via the memory.init instruction (passive data segments). See the kind member and DataKind type for more details on the active/passive distinction.

Fields§

§kind: DataKind

What kind of data segment is this? Passive or active?

§value: Vec<u8>

The data payload of this data segment.

§name: Option<String>

The name of this data, used for debugging purposes in the name custom section.

Implementations§

source§

impl Data

source

pub fn id(&self) -> DataId
