pub struct Rights { /* private fields */ }
Expand description

File descriptor rights, determining which actions may be performed.

Implementations§

The right to invoke fd_datasync.

If rights::path_open is set, includes the right to invoke path_open with fdflags::dsync.

The right to invoke fd_read and sock_recv.

If rights::fd_seek is set, includes the right to invoke fd_pread.

The right to invoke fd_seek. This flag implies rights::fd_tell.

The right to invoke fd_fdstat_set_flags.

The right to invoke fd_sync.

If rights::path_open is set, includes the right to invoke path_open with fdflags::rsync and fdflags::dsync.

The right to invoke fd_seek in such a way that the file offset remains unaltered (i.e., whence::cur with offset zero), or to invoke fd_tell.

The right to invoke fd_write and sock_send. If rights::fd_seek is set, includes the right to invoke fd_pwrite.

The right to invoke fd_advise.

The right to invoke fd_allocate.

The right to invoke path_create_directory.

If rights::path_open is set, the right to invoke path_open with oflags::creat.

The right to invoke path_link with the file descriptor as the source directory.

The right to invoke path_link with the file descriptor as the target directory.

The right to invoke path_open.

The right to invoke fd_readdir.

The right to invoke path_readlink.

The right to invoke path_rename with the file descriptor as the source directory.

The right to invoke path_rename with the file descriptor as the target directory.

The right to invoke path_filestat_get.

The right to change a file’s size (there is no path_filestat_set_size). If rights::path_open is set, includes the right to invoke path_open with oflags::trunc.

The right to invoke path_filestat_set_times.

The right to invoke fd_filestat_get.

The right to invoke fd_filestat_set_size.

The right to invoke fd_filestat_set_times.

The right to invoke path_symlink.

The right to invoke path_remove_directory.

The right to invoke path_unlink_file.

If rights::fd_read is set, includes the right to invoke poll_oneoff to subscribe to eventtype::fd_read. If rights::fd_write is set, includes the right to invoke poll_oneoff to subscribe to eventtype::fd_write.

The right to invoke sock_shutdown.

Returns an empty set of flags.

Returns the set containing all flags.

Returns the raw value of the flags currently stored.

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

Safety

The caller of the bitflags! macro can chose to allow or disallow extra bits for their bitflags type.

The caller of from_bits_unchecked() has to ensure that all bits correspond to a defined flag or that extra bits are valid for this bitflags type.

Returns true if no flags are currently stored.

Returns true if all flags are currently set.

Returns true if there are flags common to both self and other.

Returns true if all of the flags in other are contained within self.

Inserts the specified flags in-place.

Removes the specified flags in-place.

Toggles the specified flags in-place.

Inserts or removes the specified flags depending on the passed value.

Returns the intersection between the flags in self and other.

Specifically, the returned set contains only the flags which are present in both self and other.

This is equivalent to using the & operator (e.g. ops::BitAnd), as in flags & other.

Returns the union of between the flags in self and other.

Specifically, the returned set contains all flags which are present in either self or other, including any which are present in both (see Self::symmetric_difference if that is undesirable).

This is equivalent to using the | operator (e.g. ops::BitOr), as in flags | other.

Returns the difference between the flags in self and other.

Specifically, the returned set contains all flags present in self, except for the ones present in other.

It is also conceptually equivalent to the “bit-clear” operation: flags & !other (and this syntax is also supported).

This is equivalent to using the - operator (e.g. ops::Sub), as in flags - other.

Returns the symmetric difference between the flags in self and other.

Specifically, the returned set contains the flags present which are present in self or other, but that are not present in both. Equivalently, it contains the flags present in exactly one of the sets self and other.

This is equivalent to using the ^ operator (e.g. ops::BitXor), as in flags ^ other.

Returns the complement of this set of flags.

Specifically, the returned set contains all the flags which are not set in self, but which are allowed for this type.

Alternatively, it can be thought of as the set difference between Self::all() and self (e.g. Self::all() - self)

This is equivalent to using the ! operator (e.g. ops::Not), as in !flags.

Convert from a raw integer, preserving any unknown bits. See https://github.com/bitflags/bitflags/issues/263#issuecomment-957088321

expects a single right, returns None if out of bounds or > 1 bit set
