Functions

• std::string ShutdownMessage (zx::time_boot now)

  Returns the formatted string indicating the system is shutting down and doesn't guarantee any

  more logs.

• cobalt::PreviousBootEncodingVersion ToCobalt (EncodingVersion version)

  Defined at line 11 of file ../../src/developer/forensics/feedback_data/system_log_recorder/encoding/version.cc

• int main ()

  Defined at line 34 of file ../../src/developer/forensics/feedback_data/system_log_recorder/main.cc

• std::string EncodeSize (uint16_t size)

  Encodes the size of the encoded chunk as a fixed-length string that is easily decodable. This

  must be kept in sync with DecodeSize().

  The inline keyword avoids breaking the one definition rule.

  Defined at line 50 of file ../../src/developer/forensics/feedback_data/system_log_recorder/encoding/lz4_utils.h

• uint16_t DecodeSize (const char ** data_ptr)

  Reads the uint16_t value from the first two consecutive characters starting at the *data_ptr

  position and updates the *data_ptr position in order to read subsequent data.

  The inline keyword avoids breaking the one definition rule.

  Note: we do not cast directly into uint16_t to avoid alignment issues.

  Defined at line 63 of file ../../src/developer/forensics/feedback_data/system_log_recorder/encoding/lz4_utils.h

• fit::result<ReaderError, std::string> Concatenate (const std::string & logs_dir, StorageSize max_decompressed_size, Decoder * decoder, float * compression_ratio)

  Reads the encoded logs in |logs_dir|, decodes them using |decoder|, sorts log messages

  chronologically by timestamp, and aggregates consecutive repeated messages. Calculates the

  resulting |compression_ratio|.

  Returns the processed log string on success, or a ReaderError on failure.
