Struct FieldPacker 

pub struct FieldPacker<'a, 'b, T, F>
where
    T: FieldType<'a>,
    F: FieldPackHelper<'a, T>,
{ /* private fields */ }

A wrapper type that combines FieldType and FieldPackHelper to make a buffertk::Packable type.

Implementations

impl<'a, 'b, T, F> FieldPacker<'a, 'b, T, F>

where T: FieldType<'a>, F: FieldPackHelper<'a, T>,

pub fn new(tag: Tag, field_value: &'b F, field_type: PhantomData<&'a T>) -> Self

Create a new FieldPacker from the value and field type.

Trait Implementations

impl<'a, T, F> Packable for FieldPacker<'a, '_, T, F>

where T: FieldType<'a>, F: FieldPackHelper<'a, T>,

fn pack_sz(&self) -> usize

pack_sz returns the number of bytes required to serialize the Packable object.

fn pack(&self, out: &mut [u8])

pack fills in the buffer out with the packed binary representation of the Packable object. The implementor is responsible to ensure that out is exactly pack_sz() bytes and implementations are encouraged to assert this.

fn stream<W>(&self, writer: &mut W) -> Result<usize, Error>

where W: Write, Self: Sized, &'a Self: for<'a> Packable,

stream writes the object to the provided writer using the same representation that would be used in a call to pack. The implementor is responsible for making sure that the number of bytes written is exactly equal to the number of required bytes.
