Struct NodeState 

pub struct NodeState { /* private fields */ }

Canonical state of a virtual filesystem node.

Implementations

impl NodeState

pub const fn directory(mode: u32) -> Self

Construct a synthetic directory state.

pub const fn file(blob: BlobId, size: u64, mode: u32) -> Self

Construct a regular file backed by an immutable blob.

pub const fn symlink(blob: BlobId, size: u64, mode: u32) -> Self

Construct an opaque symbolic link backed by its target bytes.

pub const fn from_stamp(stamp: FileStamp) -> Self

Construct a lazily materialized state from verified host metadata.

pub const fn kind(self) -> NodeKind

Return the semantic node kind.

pub const fn size(self) -> u64

Return the node byte size.

pub const fn mode(self) -> u32

Return retained permission/mode bits.

pub const fn content(self) -> Option<ContentVersion>

Return the exact or lazy content version, if applicable.

pub const fn with_blob(self, blob: BlobId, size: u64) -> Option<Self>

Return a copy whose file/link content is now materialized.

pub fn encode_canonical(self, output: &mut Vec<u8>)

Append this state to a stable length-delimited canonical encoding.

pub fn content_equivalent(self, other: Self) -> bool

Return whether only metadata differs between two states.
