Method materialize_prefix

atomic-repository/src/repository/materialize.rs:672–702

Materialize the working copy for a specific prefix only. This is useful for partial updates when you only want to sync a subset of files. # Arguments `prefix` - Path prefix to materialize (e.g., "src/") # Returns Statistics about the materialize operation.
