+#### else blocks (let-else statements)
+
+If a let statement contains an `else` component, also known as a let-else statement,
+then the `else` component should be formatted according to the same rules as the `else` block
+in [control flow expressions (i.e. if-else, and if-let-else expressions)](./expressions.md#control-flow-expressions).
+Apply the same formatting rules to the components preceding
+the `else` block (i.e. the `let pattern: Type = initializer_expr ...` portion)
+as described [above](#let-statements)
+
+Similarly to if-else expressions, if the initializer
+expression is multi-lined, then the `else` keyword and opening brace of the block (i.e. `else {`)
+should be put on the same line as the end of the initializer
+expression with a preceding space if all the following are true:
+
+* The initializer expression ends with one or more closing
+ parentheses, square brackets, and/or braces
+* There is nothing else on that line
+* That line is not indented beyond the indent of the first line containing the `let` keyword
+
+For example:
+
+```rust
+let Some(x) = y.foo(
+ "abc",
+ fairly_long_identifier,
+ "def",
+ "123456",
+ "string",
+ "cheese",
+) else {
+ bar()
+}
+```
+
+Otherwise, the `else` keyword and opening brace should be placed on the next line after the end of the initializer expression, and should not be indented (the `else` keyword should be aligned with the `let` keyword).
+
+For example:
+
+```rust
+let Some(x) = abcdef()
+ .foo(
+ "abc",
+ some_really_really_really_long_ident,
+ "ident",
+ "123456",
+ )
+ .bar()
+ .baz()
+ .qux("fffffffffffffffff")
+else {
+ foo_bar()
+}
+```
+
+##### Single line let-else statements
+
+The entire let-else statement may be formatted on a single line if all the following are true:
+
+* the entire statement is *short*
+* the `else` block contains a single-line expression and no statements
+* the `else` block contains no comments
+* the let statement components preceding the `else` block can be formatted on a single line
+
+```rust
+let Some(1) = opt else { return };
+
+let Some(1) = opt else {
+ return;
+};
+
+let Some(1) = opt else {
+ // nope
+ return
+};
+```
+
+Formatters may allow users to configure the value of the threshold
+used to determine whether a let-else statement is *short*.
