wrapBeforeFields

default: "multi-only"

Control whether to insert line break before struct fields.

Available option values:

• "never"
• "overflow"
• "multi-only"
• "always"

All the examples below assume the print width is 50.

"never"

Line wrap will never be happened before struct fields.

(module
  (type (struct (field i32 (ref any))))
  (type (struct (field i32) (field f64)))
  (type (sub final $long-type-name (struct (field i32)))))

↓

(module
  (type (struct (field i32 (ref any))))
  (type (struct (field i32) (field f64)))
  (type
    (sub final $long-type-name (struct (field i32)))))

"overflow"

Line wrap will be happened before struct fields only when previous code exceeds the print width.

(module
  (type (struct (field i32 (ref any))))
  (type (struct (field i32) (field f64)))
  (type (sub final $long-type-name (struct (field i32)))))

↓

(module
  (type (struct (field i32 (ref any))))
  (type (struct (field i32) (field f64)))
  (type
    (sub final $long-type-name
      (struct (field i32)))))

"multi-only"

Line wrap will be happened before struct fields only when there are more than one field. Note that (field i32 i64) is considered as one field syntax.

(module
  (type (struct (field i32 (ref any))))
  (type (struct (field i32) (field f64)))
  (type (sub final $long-type-name (struct (field i32)))))

↓

(module
  (type (struct (field i32 (ref any))))
  (type
    (struct
      (field i32)
      (field f64)))
  (type
    (sub final $long-type-name (struct (field i32)))))

"always"

Line wrap will always be happened before struct fields.

(module
  (type (struct (field i32 (ref any))))
  (type (struct (field i32) (field f64)))
  (type (sub final $long-type-name (struct (field i32)))))

↓

(module
  (type
    (struct
      (field i32 (ref any))))
  (type
    (struct
      (field i32)
      (field f64)))
  (type
    (sub final $long-type-name
      (struct
        (field i32)))))
