Enum git_repository::index::write::Extensions

pub enum Extensions {
    All,
    Given {
        tree_cache: bool,
        end_of_index_entry: bool,
    },
    None,
}

A way to specify which of the optional extensions to write.

Variants

All

Fields

tree_cache: bool

Write the end-of-index-entry extension.

Only write the given optional extensions, with each extension being marked by a boolean flag.

Note: mandatory extensions

Mandatory extensions, like sdir or other lower-case ones, may not be configured here as they need to be present or absent depending on the state of the index itself and for it to be valid.

None

Write no optional extension at all for what should be the smallest possible index
