Enum zstd_safe::ResetDirective

pub enum ResetDirective {
    SessionOnly,
    Parameters,
    SessionAndParameters,
}
Expand description

What kind of context reset should be applied.

Variants§

§

SessionOnly

Only the session will be reset.

All parameters will be preserved (including the dictionary). But any frame being processed will be dropped.

It can be useful to start re-using a context after an error or when an ongoing compression is no longer needed.

§

Parameters

Only reset parameters (including dictionary or referenced prefix).

All parameters will be reset to default values.

This can only be done between sessions - no compression or decompression must be ongoing.

§

SessionAndParameters

Reset both the session and parameters.

The result is similar to a newly created context.
