Possible error cases

val compress : ?level:int -> string -> string

compress src returns a gzip-compressed version of src.

  • parameter level

    can use used to set the compression level from 0 (no compression) to 9 (highest compression).

val decompress : ?ignore_size:bool -> ?ignore_checksum:bool -> ?max_size:int -> string -> (string, [> `Gzip of error ]) result

decompress src decompresses the content from the gzip-compressed src.

  • parameter ignore_size

    may be set to true if you want to ignore the expected decompressed size information in the gzip footer. Defaults to false.

  • parameter ignore_checksum

    may be set to true if you want to ignore the expected decompressed data checksum in the gzip footer. Defaults to false.

  • parameter max_size

    may be used to specify the maximum number of bytes to decompress. Defaults to Sys.max_string_length. If src decompresses to more than max_size bytes then this function will return Error (`Gzip (Truncated truncated_content)) containing the content which was decompressed.

  • returns

    Ok content if the decompression was successful

  • returns

    Error err if there was a problem during decompression
