Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

from: Keyword

FROM [--platform=<platform>] <image> [AS <name>]
^^^^

options: Vec<Flag<'a>>

FROM [--platform=<platform>] <image> [AS <name>]
     ^^^^^^^^^^^^^^^^^^^^^^^

image: UnescapedString<'a>

FROM [--platform=<platform>] <image> [AS <name>]
                             ^^^^^^^

as_: Option<(Keyword, UnescapedString<'a>)>

FROM [--platform=<platform>] <image> [AS <name>]
                                     ^^^^^^^^^^^
