[−][src]Struct polyfuse::KernelConfig
Parameters for setting up the connection with FUSE driver and the kernel side behavior.
Implementations
impl KernelConfig
[src]
pub fn async_read(&mut self, enabled: bool) -> &mut Self
[src]
Specify that the filesystem supports asynchronous read requests.
Enabled by default.
pub fn atomic_o_trunc(&mut self, enabled: bool) -> &mut Self
[src]
Specify that the filesystem supports the O_TRUNC
open flag.
Enabled by default.
pub fn auto_inval_data(&mut self, enabled: bool) -> &mut Self
[src]
Specify that the kernel check the validity of attributes on every read.
Enabled by default.
pub fn async_dio(&mut self, enabled: bool) -> &mut Self
[src]
Specify that the filesystem supports asynchronous direct I/O submission.
Enabled by default.
pub fn parallel_dirops(&mut self, enabled: bool) -> &mut Self
[src]
Specify that the kernel supports parallel directory operations.
Enabled by default.
pub fn handle_killpriv(&mut self, enabled: bool) -> &mut Self
[src]
Specify that the filesystem is responsible for unsetting setuid and setgid bits when a file is written, truncated, or its owner is changed.
Enabled by default.
pub fn posix_locks(&mut self, enabled: bool) -> &mut Self
[src]
The filesystem supports the POSIX-style file lock.
pub fn flock_locks(&mut self, enabled: bool) -> &mut Self
[src]
Specify that the filesystem supports the flock
handling.
pub fn export_support(&mut self, enabled: bool) -> &mut Self
[src]
Specify that the filesystem supports lookups of "."
and ".."
.
pub fn dont_mask(&mut self, enabled: bool) -> &mut Self
[src]
Specify that the kernel should not apply the umask to the file mode
on create
operations.
pub fn writeback_cache(&mut self, enabled: bool) -> &mut Self
[src]
Specify that the kernel should enable writeback caching.
pub fn posix_acl(&mut self, enabled: bool) -> &mut Self
[src]
Specify that the filesystem supports POSIX access control lists.
pub fn readdirplus(&mut self, enabled: bool) -> &mut Self
[src]
Specify that the filesystem supports readdirplus
operations.
pub fn readdirplus_auto(&mut self, enabled: bool) -> &mut Self
[src]
Indicates that the kernel uses the adaptive readdirplus.
This option is meaningful only if readdirplus
is enabled.
pub fn max_readahead(&mut self, value: u32) -> &mut Self
[src]
Set the maximum readahead.
pub fn max_write(&mut self, value: u32) -> &mut Self
[src]
Set the maximum size of the write buffer.
Panic
It causes an assertion panic if the setting value is less than the absolute minimum.
pub fn max_background(&mut self, max_background: u16) -> &mut Self
[src]
Return the maximum number of pending background requests.
pub fn congestion_threshold(&mut self, threshold: u16) -> &mut Self
[src]
Set the threshold number of pending background requests that the kernel marks the filesystem as congested.
If the setting value is 0, the value is automatically calculated by using max_background.
Panics
It cause a panic if the setting value is greater than max_background
.
pub fn time_gran(&mut self, time_gran: u32) -> &mut Self
[src]
Set the timestamp resolution supported by the filesystem.
The setting value has the nanosecond unit and should be a power of 10.
The default value is 1.
