Struct ParseOptions 

pub struct ParseOptions {
    pub retain_unknown_values: Unknown<()>,
    /* private fields */
}

Available on crate feature parse2 only.

Options for parsing

Specific document and type parsing methods may use these parameters to control their parsing behaviour at run-time.

Fields

retain_unknown_values: Unknown<()>

Retain unknown values?

Some field types, especially for flags fields, have the capability to retain unknown flags. But, whereas known flags can be represented as single bits, representing unknown flags involves allocating and copying strings. Unless the document is to be reproduced, this is a waste of effort.

Each document field type affected by this option should store the unknowns as Unknown<HashSet<String>> or similar.

This feature should only be used where performance is important. For example, it is useful for types that appear in md consensus routerdescs, but less useful for types that appear only in a netstatus preamble.

This is currently used for router flags.
