Struct Preopen 

pub struct Preopen {
    pub guest: String,
    pub host: PathBuf,
}

A (guest path → host path) pair handed to wasmtime-wasi’s preopened_dir.

Preopens are derived from the component’s resolved mounts (see resolve_mounts): a bind mount preopens one host dir at its guest path, a root mount preopens the platform root(s). A component that declares only bind mounts sees ONLY those dirs (sandbox); the FsMatcher still gates per-op access on the host paths within them.

Fields

guest: String

host: PathBuf
