Struct golem_wasm_ast::core::Data

pub struct Data<Expr: Clone> { /* private fields */ }

The initial contents of a memory are zero bytes. Data segments can be used to initialize a range of memory from a static vector of bytes.

The datas component of a module defines a vector of data segments.

Like element segments, data segments have a mode that identifies them as either passive or active. A passive data segment’s contents can be copied into a memory using the memory.init instruction. An active data segment copies its contents into a memory during instantiation, as specified by a memory index and a constant expression defining an offset into that memory.

Data segments are referenced through data indices.

Trait Implementations

impl<Expr: Clone + Clone> Clone for Data<Expr>

fn clone(&self) -> Data<Expr>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Expr: Debug + Clone> Debug for Data<Expr>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<Data<IgnoredExpr>> for IgnoredData

fn from(_value: Data<IgnoredExpr>) -> Self

Converts to this type from the input type.

impl<Expr: PartialEq + Clone> PartialEq for Data<Expr>

fn eq(&self, other: &Data<Expr>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<Expr: Debug + Clone + PartialEq> Section<CoreIndexSpace, CoreSectionType> for Data<Expr>

fn index_space(&self) -> CoreIndexSpace

fn section_type(&self) -> CoreSectionType

impl<T: Clone + RetainsInstructions> TryFrom<&Data<T>> for DataSection

type Error = String

The type returned in the event of a conversion error.

fn try_from(value: &Data<T>) -> Result<Self, Self::Error>

Performs the conversion.

impl<'a, T: TryFromExprSource + Debug + Clone + PartialEq> TryFrom<Data<'a>> for Data<T>

type Error = String

The type returned in the event of a conversion error.

fn try_from(value: Data<'_>) -> Result<Self, Self::Error>

Performs the conversion.
