[−][src]Module wasihost_core::wasi_snapshot_preview1

Implementation of types and interfaces for WASI snapshot preview 1.

Modules

Native WASI types. These types can be written to and read from WASM memory.

Structs

Device	Identifier for a device containing a file system. Can be used in combination with `inode` to uniquely identify a file or directory in the filesystem.
Dircookie	A reference to the offset of a directory entry.
Dirent	A directory entry.
Dirnamlen	The type for the $d_namlen field of $dirent.
Event	An event that occurred.
EventFdReadwrite	The contents of an $event when type is `eventtype::fd_read` or `eventtype::fd_write`.
Eventrwflags	The state of the file descriptor subscribed to with `eventtype::fd_read` or `eventtype::fd_write`.
Exitcode	Exit code generated by a process when exiting.
Fd	A file descriptor handle.
Fdflags	File descriptor flags.
Fdstat	File descriptor attributes.
Filedelta	Relative offset within a file.
Filesize	Non-negative file size or length of a region within a file.
Filestat	File attributes.
Fstflags	Which file time attributes to adjust.
Inode	File serial number that is unique within its file system.
Linkcount	Number of hard links to an inode.
Lookupflags	Flags determining the method of how paths are resolved.
Oflags	Open flags used by `path_open`.
PrestatDir	The contents of a $prestat when type is `preopentype::dir`.
Riflags	Flags provided to `sock_recv`.
Rights	File descriptor rights, determining which actions may be performed.
Roflags	Flags returned by `sock_recv`.
Sdflags	Which channels on a socket to shut down.
Siflags	Flags provided to `sock_send`. As there are currently no flags defined, it must be set to zero.
Size
Subclockflags	Flags determining how to interpret the timestamp provided in `subscription_clock::timeout`.
Subscription	Subscription to an event.
SubscriptionClock	The contents of a `subscription` when type is `eventtype::clock`.
SubscriptionFdReadwrite	The contents of a `subscription` when type is type is `eventtype::fd_read` or `eventtype::fd_write`.
Timestamp	Timestamp in nanoseconds.
Userdata	User-provided value that may be attached to objects that is retained when extracted from the implementation.

Enums

Advice	File or memory access pattern advisory information.
Clockid	Identifiers for clocks.
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.
Eventtype	Type of a subscription to an event or its occurrence.
Filetype	The type of a file descriptor or file.
Preopentype	Identifiers for preopened capabilities.
Prestat	Information about a pre-opened capability.
Signal	Signal condition.
SubscriptionU	The contents of a `subscription`.
Whence	The position relative to which to set the offset of the file descriptor.

Traits

WasiImports	Functions necessary to satisfy the WASI specification.
WasiImportsExt	Extension methods for the `WasiImports` trait.
