Struct tvix_castore::proto::DirectoryNode

pub struct DirectoryNode {
    pub name: Bytes,
    pub digest: Bytes,
    pub size: u64,
}

A DirectoryNode represents a directory in a Directory.

Fields

name: Bytes

The (base)name of the directory

digest: Bytes

The blake3 hash of a Directory message, serialized in protobuf canonical form.

size: u64

Number of child elements in the Directory referred to by digest. Calculated by summing up the numbers of directories, files and symlinks, and for each directory, its size field. Used for inode number calculation. This field is precisely as verifiable as any other Merkle tree edge. Resolve digest, and you can compute it incrementally. Resolve the entire tree, and you can fully compute it from scratch. A credulous implementation won’t reject an excessive size, but this is harmless: you’ll have some ordinals without nodes. Undersizing is obvious and easy to reject: you won’t have an ordinal for some nodes.

Trait Implementations

impl Clone for DirectoryNode

fn clone(&self) -> DirectoryNode

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DirectoryNode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DirectoryNode

fn default() -> Self

Returns the “default value” for a type.

impl Hash for DirectoryNode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Message for DirectoryNode

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for DirectoryNode

fn eq(&self, other: &DirectoryNode) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
