Struct MessageBuffer

pub struct MessageBuffer(/* private fields */);

An owned container for a validated Message

Safely decoding a flatbuffer requires validating the various embedded offsets, see Verifier. This is a potentially expensive operation, and it is therefore desirable to only do this once. crate::root_as_message performs this validation on construction, however, it returns a Message borrowing the provided byte slice. This prevents storing this Message in the same data structure that owns the buffer, as this would require self-referential borrows.

MessageBuffer solves this problem by providing a safe API for a Message without a lifetime bound.
