Struct nix_compat::nar::writer::sync::Directory

pub struct Directory<'a, W: Write> {
    node: Node<'a, W>,
    prev_name: Option<Vec<u8>>,
}

Content of a NAR node that represents a directory.

Fields

node: Node<'a, W>

prev_name: Option<Vec<u8>>

Implementations

impl<'a, W: Write> Directory<'a, W>

fn new(node: Node<'a, W>) -> Self

pub fn entry(&mut self, name: &[u8]) -> Result<Node<'_, W>>

Add an entry to the directory.

The entry is simply another Node, which can then be filled like the root of a NAR (including, of course, by nesting directories).

It is the caller’s responsibility to ensure that directory entries are written in order of ascending name. If this is not ensured, this method may panic or silently produce invalid archives.

pub fn close(self) -> Result<()>

Close a directory and write terminators for the directory to the NAR.

Important: This must be called when all entries have been written in a directory, otherwise the resulting NAR file will be invalid.
