Trait for implementing a writer for Messages.

Required Associated Types

type Output

The output of this MessageWrite.

Required Methods

fn mut_data(&mut self) -> &mut [u8]

A mutable reference to the contained data.

fn data(&self) -> &[u8]

A reference to the contained data.

fn len(&self) -> usize

The length of the currently written data.

fn push_data(&mut self, data: &[u8])

Append the provided data to the end of the output.

fn push_attribute_unchecked(&mut self, attr: &dyn AttributeWrite)

Write an attribute to the end of the Message.

fn has_attribute(&self, atype: AttributeType) -> bool

Return whether this MessageWrite contains a particular attribute.

fn has_any_attribute(&self, atypes: &[AttributeType]) -> Option<AttributeType>

Return whether this MessageWrite contains any of the provided attributes and returns the attribute found.

fn finish(self) -> Self::Output

Finishes and returns the built Message.

Provided Methods

fn max_size(&self) -> Option<usize>

Return the maximum size of the output. If the output data is not bound to a fixed size, None should be returned.

Dyn Compatibility

This trait is dyn compatible.

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