Trait Implementations

impl Backend for Yaml

fn finish(&self, current: &mut Tree, desired: &Tree, existing: Existing)

Put the generated header comment above the user’s, once.

type Document = Tree

fn parse(&self, source: &str) -> Result<Tree, DocumentError>

Parse an existing source document.

fn string_leaf(&self, node: &Entry) -> Result<Option<String>, DocumentError>

The text of node when it is a string, None for any other kind of value.

fn descend<'n>( &self, node: &'n Entry, key: &str, path: &[String], ) -> Result<Option<&'n Entry>, DocumentError>

The child key of node, which sits at path. Backends fail here when a node on the way cannot be read through.

fn explain(&self, current: &Tree, error: MergeError) -> DocumentError

The error for a merge that failed against current. Backends can name a cause more precisely than the generic conflict.

fn format(&self) -> Format

The format this backend reads and writes.

fn build(&self, desired: &Annotated) -> Result<Tree, DocumentError>

Build the desired document from its annotated value.

fn read_string( &self, source: &str, path: &[String], ) -> Result<Option<String>, DocumentError>

The string at path in source, or None when a key on the way is absent.

fn reconcile( &self, desired: &Annotated, source: &Source<'_>, ownership: &Ownership, ) -> Result<Vec<u8>, DocumentError>

Reconcile a desired value against the current source.

impl Clone for Yaml

fn clone(&self) -> Yaml

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Yaml

impl Debug for Yaml

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

Formats the value using the given formatter.
