DO NOT EDIT. + +// Package types represents the imported interface "wasi:filesystem/types@0.2.0". +// +// WASI filesystem is a filesystem API primarily intended to let users run WASI +// programs that access their files on their existing filesystems, without +// significant overhead. +// +// It is intended to be roughly portable between Unix-family platforms and +// Windows, though it does not hide many of the major differences. +// +// Paths are passed as interface-type `string`s, meaning they must consist of +// a sequence of Unicode Scalar Values (USVs). Some filesystems may contain +// paths which are not accessible by this API. +// +// The directory separator in WASI is always the forward-slash (`/`). +// +// All paths in WASI are relative paths, and are interpreted relative to a +// `descriptor` referring to a base directory. If a `path` argument to any WASI +// function starts with `/`, or if any step of resolving a `path`, including +// `..` and symbolic link steps, reaches a directory outside of the base +// directory, or reaches a symlink to an absolute or rooted path in the +// underlying filesystem, the function fails with `error-code::not-permitted`. +// +// For more information about WASI path resolution and sandboxing, see +// [WASI filesystem path resolution]. +// +// [WASI filesystem path resolution]: https://github.com/WebAssembly/wasi-filesystem/blob/main/path-resolution.md +package types + +import ( + wallclock "github.com/rvolosatovs/west/go/bindings/wasi/clocks/wall-clock" + ioerror "github.com/rvolosatovs/west/go/bindings/wasi/io/error" + "github.com/rvolosatovs/west/go/bindings/wasi/io/streams" + "github.com/ydnar/wasm-tools-go/cm" +) + +// FileSize represents the u64 "wasi:filesystem/types@0.2.0#filesize". +// +// File size or length of a region within a file. +// +// type filesize = u64 +type FileSize uint64 + +// DescriptorType represents the enum "wasi:filesystem/types@0.2.0#descriptor-type". +// +// The type of a filesystem object referenced by a descriptor. +// +// Note: This was called `filetype` in earlier versions of WASI. +// +// enum descriptor-type { +// unknown, +// block-device, +// character-device, +// directory, +// fifo, +// symbolic-link, +// regular-file, +// socket +// } +type DescriptorType uint8 + +const ( + // The type of the descriptor or file is unknown or is different from + // any of the other types specified. + DescriptorTypeUnknown DescriptorType = iota + + // The descriptor refers to a block device inode. + DescriptorTypeBlockDevice + + // The descriptor refers to a character device inode. + DescriptorTypeCharacterDevice + + // The descriptor refers to a directory inode. + DescriptorTypeDirectory + + // The descriptor refers to a named pipe. + DescriptorTypeFIFO + + // The file refers to a symbolic link inode. + DescriptorTypeSymbolicLink + + // The descriptor refers to a regular file inode. + DescriptorTypeRegularFile + + // The descriptor refers to a socket. + DescriptorTypeSocket +) + +var stringsDescriptorType = [8]string{ + "unknown", + "block-device", + "character-device", + "directory", + "fifo", + "symbolic-link", + "regular-file", + "socket", +} + +// String implements [fmt.Stringer], returning the enum case name of e. +func (e DescriptorType) String() string { + return stringsDescriptorType[e] +} + +// DescriptorFlags represents the flags "wasi:filesystem/types@0.2.0#descriptor-flags". +// +// Descriptor flags. +// +// Note: This was called `fdflags` in earlier versions of WASI. +// +// flags descriptor-flags { +// read, +// write, +// file-integrity-sync, +// data-integrity-sync, +// requested-write-sync, +// mutate-directory, +// } +type DescriptorFlags uint8 + +const ( + // Read mode: Data can be read. + DescriptorFlagsRead DescriptorFlags = 1 << iota + + // Write mode: Data can be written to. + DescriptorFlagsWrite + + // Request that writes be performed according to synchronized I/O file + // integrity completion.
