• Reference
• Object

Overview

BakedFile represents a virtual file in a BakedFileSystem.

Usage

file = MyFileSystem.get("hello-world.txt")
file.path        # => "hello-world.txt"
file.size        # => 12
file.gets_to_end # => "Hello World\n"
file.compressed? # => false

Constructors

• .new(path : String, size : Int32, compressed : Bool, slice : Bytes)

Instance Method Summary

• #compressed? : Bool

  Returns whether this file is compressed.

• #compressed_size

  Returns the compressed size of this virtual file.

• #path : String

  Returns the path in the virtual file system.

• #read(slice : Bytes)

  Reads at most slice.size bytes from this IO into slice.

• #read

  Return the data for this file as a String.

• #rewind

  Rewinds this IO.

• #size : Int32

  Returns the size of this virtual file.

• #to_encoded(compressed = true)

  Return the data for this file as a URL-safe Base64-encoded String.

• #to_slice(compressed)

  Return the file's data as a Slice(UInt8)

• #to_slice : Bytes

  Returns a Bytes holding the (compressed) content of this virtual file.

• #write(slice : Bytes) : Nil

  Writes the contents of slice into this IO.

• #write_to_io(io, compressed = true)

  Write the file's data to the given IO, minimizing any memory copies or unnecessary conversions.
