Phoenix.HTML v2.12.0 Phoenix.HTML.Safe protocol View Source
Defines the HTML safe protocol.
In order to promote HTML safety, Phoenix templates
do not use
Kernel.to_string/1 to convert data types to
strings in templates. Instead, Phoenix uses this
protocol which must be implemented by data structures
and guarantee that a HTML safe representation is returned.
Furthermore, this protocol relies on iodata, which provides better performance when sending or streaming data to the client.
