DictionaryAccess

Struct DictionaryAccess 

Source
pub struct DictionaryAccess { /* private fields */ }
Expand description

一份词库访问租约,持有期间别的进程(和本进程里的其他租约)按 DictionaryAccess::try_session、DictionaryAccess::try_maintenance 的规则互斥。

Implementations§

Source§

impl DictionaryAccess

Source

pub fn try_session(user: &Path, dictionaries: &Path) -> Result<Option<Self>>

不等待地取共享租约(会话用)。None 表示正在维护。

Source

pub fn try_maintenance(user: &Path, dictionaries: &Path) -> Result<Option<Self>>

不等待地取独占的维护租约。None 表示还有会话或别的维护持着租约。

Source

pub fn directory(&self, path: &Path) -> Result<File>

取租约时打开的那个根目录的句柄(复制一份)。之后这个路径被换成别的目录,句柄仍指向取锁时的那个。path 不是租约的根目录时报 NotFound。
