Struct LookupContext 

pub struct LookupContext {
    pub symlink_mode: SymlinkMode,
    pub remaining_follows: u8,
    pub must_be_directory: bool,
    pub resolve_flags: ResolveFlags,
    pub resolve_base: ResolveBase,
}

The context passed during namespace lookups.

Namespace lookups need to mutate a shared context in order to correctly count the number of remaining symlink traversals.

Fields

symlink_mode: SymlinkMode

The SymlinkMode for the lookup.

As the lookup proceeds, the follow count is decremented each time the lookup traverses a symlink.

remaining_follows: u8

The number of symlinks remaining the follow.

Each time path resolution calls readlink, this value is decremented.

must_be_directory: bool

Whether the result of the lookup must be a directory.

For example, if the path ends with a / or if userspace passes O_DIRECTORY. This flag can be set to true if the lookup encounters a symlink that ends with a /.

resolve_flags: ResolveFlags

Resolve flags passed to openat2. Empty if the lookup originated in any other syscall.

resolve_base: ResolveBase

Base directory for the lookup. Set only when either RESOLVE_BENEATH or RESOLVE_IN_ROOT is passed to openat2.
