Trait ResolveOptionalWithOpenAPI 

pub trait ResolveOptionalWithOpenAPI<T> {
    // Required method
    fn resolve_optional<'a>(
        &'a self,
        openapi: &'a OpenAPI,
    ) -> Result<Option<&'a T>, ResolveError>;
}

Resolves an optional ReferenceOr<T> field.

Kept separate from ResolveWithOpenAPI so that an absent field — which is valid — stays distinguishable from a broken reference.

Required Methods

fn resolve_optional<'a>( &'a self, openapi: &'a OpenAPI, ) -> Result<Option<&'a T>, ResolveError>

Returns Ok(None) if the field is absent, and an error only if a reference that is present cannot be resolved.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
