Struct FsConfig 

pub struct FsConfig {
    pub tag: String,
    pub source: String,
    pub num_threads: usize,
    pub writeback_cache: bool,
    pub cache_profile: CacheProfile,
    pub cache_timeout: u64,
    pub negative_cache_ttl: u64,
}

Filesystem configuration.

Fields

tag: String

Tag for virtiofs mount.

source: String

Host directory to share.

num_threads: usize

Number of worker threads.

writeback_cache: bool

Enable writeback caching.

cache_profile: CacheProfile

Cache profile controlling FUSE entry/attr timeouts. Takes precedence over cache_timeout when set.

cache_timeout: u64

Cache timeout for directory entries and attributes (seconds). Used as a fallback when cache_profile is not explicitly set. Higher values reduce FUSE round-trips but delay visibility of host filesystem changes inside the guest.

negative_cache_ttl: u64

Negative lookup cache TTL (seconds). Caches ENOENT results to avoid repeated stat() calls for non-existent paths.
