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
None
Write no optional extension at all for what should be the smallest possible index
