class VmCompressionStrategy

Defined at line 91 of file ../../zircon/kernel/vm/include/vm/compression.h

Defines the interface for different compression algorithms.

Instances of this class may be accessed concurrently.

Public Methods

CompressResult Compress (const void * src, void * dst, size_t dst_limit)

void Decompress (const void * src, size_t src_len, void * dst)

Decompress the data at |src| into |dst|. The input is assumed to have been produced by

|Compress| and this method cannot fail. Similar to the input of |Compress| being assumed to be

a page size, the |dst| output here is assumed to be of page size and will be exactly filled.

No guarantee on the alignment of |src| or |dst| is provided, and the caller is free to provide

pointers with arbitrary byte alignment.

TODO(https://fxbug.dev/42138396): Consider requiring an alignment if needed by decompressors.

void Dump ()

Perform an information dump of the internal state to the debuglog.
