Hackage :: [Package]

from-string: Instances of 'From' for common string types

[ apache, bytestring, library, string, text ] [ Propose Tags ] [ Report a vulnerability ]

Convenient "sane default" conversion from/to strict ByteString, lazy ByteString, ByteString Builder, ShortByteString, strict Text, lazy Text, Text Builder, and String. When the conversions crosses the boundary of the byte types and the textual types, UTF-8 is assumed.

Readme for from-string-1.0.0.1

[back to package description]

from-string

Note that this package is a part of the "project" that includes from and from-string. For the general rationale behind this idea, see README.md under the project root.

This Haskell library package provides the From typeclass instances for the conversion of following types:

  • String
  • bytestring:
    • Strict ByteString
    • Lazy ByteString
    • Builder for ByteString
    • ShortByteString
  • text:
    • Strict Text
    • Lazy Text
    • Builder for Text

Whenever encoding/decoding happens, this library assumes that the aforementioned types internally contains either

  • a sequence of Unicode characters, or
  • a sequence of bytes in UTF-8.

This should be a reasonable assumption for practical software development. If you need any other assumption, you should specify the accurate conversion in the code, instead of 'from'.

See the From.String module documentation for more detail.
