Constructors

new(io : IO, compression_ratio : Float64 = Snappy::Consts::MIN_COMPRESSION_RATIO, sync_close : Bool = false)

Creates a new writer to the given io.

new(filename : String, compression_ratio = Snappy::Consts::MIN_COMPRESSION_RATIO)

Creates a new writer to the given filename.

open(io : IO, sync_close = false, compression_ratio = Snappy::Consts::MIN_COMPRESSION_RATIO, &)

Creates a new writer to the given io, yields it to the given block, and closes it at the end.

open(filename : String, compression_ratio = Snappy::Consts::MIN_COMPRESSION_RATIO, &)
