Module effector

Modules

memory_and_snapshot 🔒

process_exit 🔒

save_event 🔒

syscalls 🔒

thread_exit 🔒

thread_state 🔒

Macros

bail 🔒

Return early with an error.

Structs

Bytes 🔒

A cheaply cloneable and sliceable chunk of contiguous memory.

EpollEventCtl 🔒

ExitCode 🔒

Fdflags 🔒

File descriptor flags.

Fdflagsext 🔒

Fstflags 🔒

Which file time attributes to adjust. TODO: wit appears to not have support for flags repr (@witx repr u16)

FunctionEnvMut 🔒

A temporary handle to a FunctionEnv.

JournalEffector

The journal effector is an adapter that will be removed in a future refactor. Its purpose is to put the code that does mappings from WASM memory through its abstractions into concrete journal objects that can be stored. Instead of this what should be done is that the syscalls themselves can be represented as a strongly typed object that can be passed directly to the journal but in order to do this we require an extensive refactoring of the WASIX syscalls which is not in scope at this time.

MutexGuard 🔒

An RAII implementation of a “scoped lock” of a mutex. When this structure is dropped (falls out of scope), the lock will be unlocked.

Oflags 🔒

Open flags used by path_open. TODO: wit appears to not have support for flags repr (@witx repr u16)

Range 🔒

A (half-open) range bounded inclusively below and exclusively above (start..end).

Rights 🔒

File descriptor rights, determining which actions may be performed.

SystemTime 🔒

A measurement of the system clock, useful for talking to external entities like the file system or other processes.

WasmPtr 🔒

A zero-cost type that represents a pointer to something in Wasm linear memory.

__wasi_ciovec_t 🔒

Enums

Advice 🔒

File or memory access pattern advisory information.

Cow 🔒

A clone-on-write smart pointer.

EpollCtl 🔒

Epoll operation.

Errno 🔒

Error codes returned by functions. Not all of these error codes are returned by the functions provided by this API; some are used in higher-level library layers, and others are provided merely for alignment with POSIX.

Snapshot0Clockid 🔒

Identifiers for clocks, snapshot0 version.

Whence 🔒

Traits

MemorySize 🔒

Trait for the Memory32 and Memory64 marker types.

Type Aliases

Fd 🔒

A file descriptor handle.

Filesize 🔒

Non-negative file size or length of a region within a file.

LookupFlags 🔒

Timestamp 🔒

Timestamp in nanoseconds.
