Struct PhysicalSpaceGuard 

pub struct PhysicalSpaceGuard { /* private fields */ }

Implementations

impl PhysicalSpaceGuard

pub fn new(minimum_free_bytes: u64) -> Result<Self>

pub fn has_refused(&self) -> bool

Any admission failure ends this guarded writer; a fresh process may retry.

pub fn refusal_error(&self) -> Error

pub fn status(&self) -> String

pub fn install(&self, options: &mut EnvOpenOptions) -> Result<()>

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

Admit each namespace change on its actual parent filesystem. Existing directories require no admission, preserving duplicate/no-op operation.

pub fn admit_file(&self, file: &File, offset: u64, length: usize) -> Result<()>

pub fn write_all(&self, file: &mut File, data: &[u8]) -> Result<()>
