Types ¶
type Function ¶
type Function struct {
// contains filtered or unexported fields
}
Function is an exported wazero guest function.
type Global ¶
type Global struct {
// contains filtered or unexported fields
}
Global is an exported wazero guest global.
type Instance ¶
type Instance struct {
// contains filtered or unexported fields
}
Instance is a running wazero guest and its active guest calls. Only the goroutine running the guest uses it.
func (*Instance) ExportedFunction ¶
ExportedFunction returns an exported function, or nil when the guest does not export it.
func (*Instance) ExportedGlobal ¶
ExportedGlobal returns an exported global, or nil when the guest does not export it.
type Memory ¶
type Memory struct {
// contains filtered or unexported fields
}
Memory is the linear memory of a wazero guest.
func (*Memory) ReadByteAt ¶
ReadByteAt returns the byte at offset.
func (*Memory) ReadUint32Le ¶
ReadUint32Le returns the little-endian uint32 at offset.
func (*Memory) ReadUint64Le ¶
ReadUint64Le returns the little-endian uint64 at offset.
func (*Memory) WriteByteAt ¶
WriteByteAt writes one byte at offset.
func (*Memory) WriteUint32Le ¶
WriteUint32Le writes a little-endian uint32 at offset.
type Module ¶
type Module struct {
// contains filtered or unexported fields
}
Module is a compiled wazero module.
type Runtime ¶
type Runtime struct {
// contains filtered or unexported fields
}
Runtime is a wazero runtime with threads enabled. Canceling the context of a running guest stops it, even while it computes.
func (*Runtime) Define ¶
func (r *Runtime) Define(ctx context.Context, module string, fns map[string]engine.HostFunction) error
Define provides fns to guests as the imports of module.
func (*Runtime) Snapshotter ¶
func (r *Runtime) Snapshotter(ctx context.Context) engine.Snapshotter
Snapshotter returns the snapshotter of the host call running under ctx, or nil when its guest is not transformed with Asyncify.
