Struct Root

Source
pub struct Root(/* private fields */);
Expand description

The wrapper type for the underlying type which will be used to represent the “root” identifier for an crate::AtomId. For git, this is a [gix::ObjectId] representing the original commit made in the repositories history.

The wrapper helps disambiguate at the type level between object ids and the root id.

Methods from Deref<Target = ObjectId>§

pub fn kind(&self) -> Kind

Returns the kind of hash used in this instance.

pub fn as_slice(&self) -> &[u8]

Return the raw byte slice representing this hash.

pub fn is_null(&self) -> bool

Returns true if this hash consists of all null bytes.

pub fn is_empty_blob(&self) -> bool

Returns true if this hash is equal to an empty blob.

pub fn is_empty_tree(&self) -> bool

Returns true if this hash is equal to an empty tree.

Methods from Deref<Target = oid>§

pub fn kind(&self) -> Kind

The kind of hash used for this instance.

pub fn first_byte(&self) -> u8

The first byte of the hash, commonly used to partition a set of object ids.

pub fn as_bytes(&self) -> &[u8]

Interpret this object id as raw byte slice.

pub fn to_hex_with_len(&self, len: usize) -> HexDisplay<'_>

Return a type which can display itself in hexadecimal form with the len amount of characters.

pub fn to_hex(&self) -> HexDisplay<'_>

Return a type which displays this oid as hex in full.

pub fn is_null(&self) -> bool

Returns true if this hash consists of all null bytes.

pub fn hex_to_buf<'a>(&self, buf: &'a mut [u8]) -> &'a mut str

Write ourselves to the out in hexadecimal notation, returning the hex-string ready for display.

Panics if the buffer isn’t big enough to hold twice as many bytes as the current binary size.

pub fn write_hex_to(&self, out: &mut dyn Write) -> Result<(), Error>

Write ourselves to out in hexadecimal notation.

pub fn verify(&self, expected: &oid) -> Result<(), Error>

Verify that self matches the expected object ID.

Returns an [Error] containing both object IDs if they differ.

impl<'a> Publish<Root> for GitContext<'a>

Source§

fn publish<C>( &self, paths: C, remotes: HashMap<AtomTag, (Version, ObjectId)>, ) -> Vec<GitResult<GitOutcome>>
where C: IntoIterator<Item = PathBuf>,

Publishes atoms.

This function processes a collection of paths, each representing an atom to be published. The publishing process includes path normalization, existence checks, and actual publishing attempts.

§Path Normalization
  • First attempts to interpret each path as relative to the caller’s current location inside the repository.
  • If normalization fails (e.g., in a bare repository), falls back to treating the path as already relative to the repo root.
  • The normalized path is used to search the Git history, not the file system.
§Publishing Process

For each path:

  1. Normalizes the path (as described above).
  2. Checks if the atom already exists in the repository.
    • If it exists, the atom is skipped, and a log message is generated.
  3. Attempts to publish the atom.
    • If successful, the atom is added to the repository.
    • If any error occurs during publishing, the atom is skipped, and an error is logged.
§Error Handling
  • The function aims to process all provided paths, even if some fail.
  • Errors and skipped atoms are collected as results but do not halt the overall process.
  • The function continues until all the atoms have been processed.
§Return Value

Returns a vector of results types (Vec<Result<PublishOutcome<T>, Self::Error>>), where the outter result represents whether an atom has failed, and the inner result determines whether an atom was safely skipped, e.g. because it already exists..
