Enum gix_index::write::Extensions

source ·
pub enum Extensions {
    All,
    Given {
        tree_cache: bool,
        end_of_index_entry: bool,
    },
    None,
}
Expand description

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

Variants§

§

All

Writes all available optional extensions to avoid losing any information.

§

Given

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.

Fields

§tree_cache: bool

Write the tree-cache extension, if present.

§end_of_index_entry: bool

Write the end-of-index-entry extension.

§

None

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