Unconditional serde_bytes::deserialize

[dtolnay]

This cfg is from back when deserialize had this signature, before 6a14f76, so it didn't make sense without Vec existing:

bytes/src/lib.rs

Lines 131 to 134 in 29f7e7a

	#[cfg(any(feature = "std", feature = "collections"))]
	pub fn deserialize<'de, T, D>(deserializer: D) -> Result<T, D::Error>
	where T: From<Vec<u8>>,
	D: Deserializer<'de>
