Struct Serializer

Source 
pub struct Serializer<W, A, S> {
    pub writer: W,
    pub allocator: A,
    pub sharing: S,
}
Expand description

A serializer built from composeable pieces.

Fields§

§writer: W

The writer of the serializer.

§allocator: A

The allocator of the serializer.

§sharing: S

The pointer sharing of the serializer.

Implementations§

Source§

impl<W, A, S> Serializer<W, A, S>

Source

pub fn new(writer: W, allocator: A, sharing: S) -> Self

Creates a new serializer from a writer, allocator, and pointer sharing.

Source

pub fn into_raw_parts(self) -> (W, A, S)

Consumes the serializer and returns the components.

Source

pub fn into_writer(self) -> W

Consumes the serializer and returns the writer.

The allocator and pointer sharing are discarded.
