[−][src]Struct polyfuse::KernelConfig

pub struct KernelConfig { /* fields omitted */ }

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.
