Expand description

Wraps a buffer to be written by ToSql with additional backend specific utilities.

Implementations§

Construct a new Output

Consume the current Output structure to access the inner buffer type

This function is only useful for people implementing their own Backend.

Returns the backend’s mechanism for dynamically looking up type metadata at runtime, if relevant for the given backend.

Set the inner buffer to a specific value

Checkout the documentation of the type of BindCollector::Buffer for your specific backend for supported types.

Call this method whenever you pass an instance of Output<DB> by value.

Effectively copies self, with a narrower lifetime. When passing a reference or a mutable reference, this is normally done by rust implicitly. This is why you can pass &mut Foo to multiple functions, even though mutable references are not Copy. However, this is only done implicitly for references. For structs with lifetimes it must be done explicitly. This method matches the semantics of what Rust would do implicitly if you were passing a mutable reference
