Struct wasmer_vm::VMTable

pub struct VMTable {
    pub from: Arc<dyn Table>,
    pub instance_ref: Option<WeakOrStrongInstanceRef>,
}

A table export value.

Fields

from: Arc<dyn Table>

Pointer to the containing Table.

instance_ref: Option<WeakOrStrongInstanceRef>

A “reference” to the instance through the InstanceRef. None if it is a host table.

Implementations

impl VMTable

pub fn ty(&self) -> &TableType

Get the table type for this exported table

pub fn style(&self) -> &TableStyle

Get the style for this exported table

pub fn same(&self, other: &Self) -> bool

Returns whether or not the two VMTables refer to the same Memory.

pub fn upgrade_instance_ref(&mut self) -> Option<()>

Converts the stored instance ref into a strong InstanceRef if it is weak. Returns None if it cannot be upgraded.

Trait Implementations

impl Clone for VMTable

fn clone(&self) -> VMTable

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VMTable

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

Formats the value using the given formatter.

impl From<VMTable> for VMExtern

fn from(table: VMTable) -> Self

Performs the conversion.

impl MemoryUsage for VMTable

fn size_of_val(&self, visited: &mut dyn MemoryUsageTracker) -> usize

Returns the size of the referenced value in bytes.

impl Send for VMTable

Safety

This is correct because there is no non-threadsafe logic directly in this type; correct use of the raw table from multiple threads via definition requires unsafe and is the responsibilty of the user of this type.

impl Sync for VMTable

Safety

This is correct because the values directly in definition should be considered immutable and the type is both Send and Clone (thus marking it Sync adds no new behavior, it only makes this type easier to use)
