Trait WireReadRef 

pub trait WireReadRef {
    // Required method
    fn read_wire_ref<'a>(
        curs: &mut WireCursor<'a>,
        size: usize,
    ) -> Result<&'a Self, WireError>;
}

Deserialization to an immutable reference of a data type from the wire.

A type that implements this trait guarantees that it can be constructed using a given number of bytes from the provided WireCursor. If the bytes contained on the wire cannot be converted into a reference of a valid instance of the object, an error will be returned instead of the reference.

Required Methods

fn read_wire_ref<'a>( curs: &mut WireCursor<'a>, size: usize, ) -> Result<&'a Self, WireError>

Consumes exactly size bytes from curs and returns an immutable reference of the specified type, or returns a WireError on failure.

The returned reference must not outlive the lifetime of the buffer that it references, though it may outlive the WireReader used to construct it.

The generic boolean E designates the intended endianness of the data being read. If E is set to true, then the data will be deserialized in big endian format; if false, it will be deserialized in little endian.

Errors

WireError::InsufficientBytes - less than size bytes remained on the cursor.

WireError::InvalidData - the bytes retrieved from curs could not be used to construct a valid reference of the type.

WireError::Internal - an internal error occurred in the wire-rs library

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
