serde-rs/serde v1.0.90

on GitHub

Add an attribute #[serde(crate = "path::to::serde")] which replaces the use of extern crate serde in the generated code; this is intended for crates that invoke Serde derives from a macro and need to refer to serde through their own re-export rather than requiring callers to list Serde in Cargo.toml (#1499, thanks @sgrif)

#[derive(Deserialize)]
#[serde(crate = "__tw::codegen::serde")]
struct S { ... }

// expands to:
impl<'de> __tw::codegen::serde::Deserialize<'de> for S {
    ...
}
