Struct PerProcessState 

pub struct PerProcessState {
    pub virtual_cwd: Option<String>,
    pub brk_base: Option<u64>,
    pub cow_dir_cache: HashMap<u32, (String, Vec<Vec<u8>>)>,
    pub procfs_dir_cache: HashMap<(u32, String), Vec<Vec<u8>>>,
}

All per-process supervisor state for one tracked child. One instance lives per PidKey, owned by ProcessIndex behind an Arc<AsyncMutex<…>>. Cleanup on process exit is one operation: ProcessIndex::unregister drops the index’s Arc, and the supervisor’s per-handler clones drop along with their tasks.

Fields

virtual_cwd: Option<String>

Logical cwd while the process is chdir’d into a COW-only directory. None means “use kernel-reported cwd”.

brk_base: Option<u64>

Recorded brk base for memory accounting. None until first brk.

cow_dir_cache: HashMap<u32, (String, Vec<Vec<u8>>)>

COW directory dirent cache. Keyed by child’s fd; value is (host target path, sorted dirent bytes left to return). Entries are invalidated when the fd is reused for a different directory.

procfs_dir_cache: HashMap<(u32, String), Vec<Vec<u8>>>

/proc directory dirent cache. Keyed by (child fd, target path); same drain-on-EOF semantics as cow_dir_cache.

Trait Implementations

impl Default for PerProcessState

fn default() -> PerProcessState

Returns the “default value” for a type.
