kumo.file_type
Since: Dev Builds Only
The functionality described in this section requires a dev build of KumoMTA. You can obtain a dev build by following the instructions in the Installation section.
The kumo.file_type module includes functions that can help you to reason
about the file type of a sequence of bytes, or about the file types associated
with mime media types or filename extensions.
The underlying implementation of this module is provided by the file_type Rust crate.
FileTypeResult
The functions in this module all return a file type result which has the following shape:
local file_type = {
-- The human readable name of the file type
name = 'Java class file',
-- The file type extensions, not including the dot
extensions = { 'class' },
-- The [RFC 2046 MIME Media Types](https://www.rfc-editor.org/rfc/rfc2046.html)
-- associated with this file type
media_types = {
'application/java',
'application/java-byte-code',
'application/java-vm',
'application/x-httpd-java',
'application/x-java',
'application/x-java-class',
'application/x-java-vm',
},
