AtomicFileWriter

Struct AtomicFileWriter 

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

原子文件写入器

使用临时文件 + 重命名模式实现原子写入。 在 Windows 上使用 os.replace(),在 NTFS 上是原子的。 在 Unix 上使用 rename(),在相同文件系统上是原子的。

Implementations§

Source§

impl AtomicFileWriter

Source

pub fn new() -> Self

创建新的原子写入器

Source

pub fn with_sync(self, sync: bool) -> Self

配置是否在写入后同步

Source

pub fn with_verify(self, verify: bool) -> Self

配置是否验证写入

Source

pub fn write_atomic(&self, filepath: &Path, content: &str) -> Layer2Result<()>

原子写入内容到文件

§Arguments
  • filepath - 目标文件路径
  • content - 要写入的内容
§Returns

成功返回 Ok(()),失败返回错误信息

Source

pub fn safe_remove(&self, path: &Path) -> Layer2Result<()>
