[−][src]Module mail::header_encoding
This module provides the encoding buffer.
The encoding buffer is the buffer header implementations write there data to. It provides a view special aspects to make it more robust.
For example it handles the writing of trailing newlines for headers (if they don't do it) and it fails if you write utf-8 data (in the header) to an buffer which knows that the used mail type doesn't support it.
There is also a special tracing (cargo) feature which
will make it's usage slower, but which will keep track of
what data was inserted in which way making debugging and
writing tests easier. (Through it should only be enabled
for testing and maybe debugging in some cases).
Structs
| EncodeClosure | A wrapper for an closure making it implement |
| EncodeFn | A wrapper for an function making it implement |
| EncodingBuffer | EncodingBuffer for a Mail providing a buffer for encodable traits. |
| EncodingWriter | A handle providing method to write to the underlying buffer keeping track of newlines the current line length and places where the line can be broken so that the soft line length limit (78) and the hard length limit (998) can be kept. |
