### 3.1.73 MultiMeasureRest

MultiMeasureRest objects are created by: Multi_measure_rest_engraver.

Standard settings:

> `expand-limit` (integer):

>   `10`

>   Maximum number of measures expanded in church rests.

> `hair-thickness` (number):

>   `2.0`

>   Thickness of the thin line in a bar line.

> `padding` (dimension, in staff space):

>   `1`

>   Add this much extra space between objects that are next to each other.

> `round-up-exceptions` (list):

>   `'()`

>   A list of pairs where car is the numerator and cdr the denominator of a moment. Each pair in this list means that the multi-measure rests of the corresponding length will be rounded up to the longer rest. See round-up-to-longer-rest.

> `spacing-pair` (pair):

>   `'(break-alignment . break-alignment)`

>   A pair of alignment symbols which set an object’s spacing relative to its left and right `BreakAlignment`s.

>   For example, a `MultiMeasureRest` will ignore prefatory items at its bounds (i.e., clefs, key signatures and time signatures) using the following override:

>   >     \override MultiMeasureRest
>   >       #'spacing-pair = #'(staff-bar . staff-bar)

> `springs-and-rods` (boolean):

>   `ly:multi-measure-rest::set-spacing-rods`

>   Dummy variable for triggering spacing routines.

> `stencil` (stencil):

>   `ly:multi-measure-rest::print`

>   The symbol to print.

> `thick-thickness` (number):

>   `6.6`

>   Bar line thickness, measured in `line-thickness`.

> `usable-duration-logs` (list):

>   `'(-3 -2 -1 0)`

>   List of `duration-log`s that can be used in typesetting the grob.

> `Y-extent` (pair of numbers):

>   `#<unpure-pure-container #<primitive-procedure ly:multi-measure-rest::height> >`

>   Extent (size) in the Y direction, measured in staff-space units, relative to object’s reference point.

> `Y-offset` (number):

>   `#<unpure-pure-container #<primitive-procedure ly:staff-symbol-referencer::callback> >`

>   The vertical amount that this object is moved relative to its Y-parent.

This object supports the following interface(s): font-interface, grob-interface, multi-measure-interface, multi-measure-rest-interface, rest-interface, spanner-interface and staff-symbol-referencer-interface.
