Struct ParsePixelFormatError 

#[non_exhaustive]
pub struct ParsePixelFormatError;

The error PixelFormat’s FromStr returns at the no-alloc tier.

Since 0.5.0 this is no longer FromStr::Err at the alloc / std tier. There the vocabulary is open and the parse is total, so the associated type is Infallible and the signature says what the behaviour always was. The type itself is unchanged and still exported: the lean build returns it, and code that names it keeps compiling.

Opaque and sealed: the input is deliberately not retained (this type is reachable only at the no-alloc tier, where there is nowhere to put an owned copy, and the input is attacker-controlled on the deserialization path). #[non_exhaustive] keeps it constructible only here, so it can grow structure later without breaking callers.
