If a leaf part's body content is omitted, return the encoded length and transfer encoding in --format=json output. This information may be used by the consumer, e.g. to decide whether to download a large attachment over a slow link. Returning the _encoded_ content length is more efficient than returning the _decoded_ content length. Returning the transfer encoding allows the consumer to estimate the decoded content length.

This file describes the schemata used for notmuch's structured output
|
|
format (currently JSON and S-Expressions).
|
|
|
|
[]'s indicate lists. List items can be marked with a '?', meaning
|
|
they are optional; or a '*', meaning there can be zero or more of that
|
|
item. {}'s indicate an object that maps from field identifiers to
|
|
values. An object field marked '?' is optional. |'s indicate
|
|
alternates (e.g., int|string means something can be an int or a
|
|
string).
|
|
|
|
For S-Expression output, lists are printed delimited by () instead of
|
|
[]. Objects are printed as p-lists, i.e. lists where the keys and values
|
|
are interleaved. Keys are printed as keywords (symbols preceded by a
|
|
colon), e.g. (:id "123" :time 54321 :from "foobar"). Null is printed as
|
|
nil, true as t and false as nil.
|
|
|
|
This is version 1 of the structured output format.
