Create an error for a missing method specialization. Defaults to panicking with type, trait & method names. `S` is the encoder/decoder state type, `T` is the type being encoded/decoded, and the arguments are the names of the trait and method that should've been overridden. Read more

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
