pub struct Encoder { /* private fields */ }

Implementations

impl Encoder

pub fn new(writer: Vec<u8>) -> Self

pub fn begin_map(&mut self) -> &mut Self

pub fn begin_array(&mut self) -> &mut Self

pub fn boolean(&mut self, x: bool) -> &mut Self

pub fn byte(&mut self, x: i8) -> &mut Self

pub fn short(&mut self, x: i16) -> &mut Self

pub fn integer(&mut self, x: i32) -> &mut Self

pub fn long(&mut self, x: i64) -> &mut Self

pub fn float(&mut self, x: f32) -> &mut Self

pub fn double(&mut self, x: f64) -> &mut Self

pub fn null(&mut self) -> &mut Self

pub fn end(&mut self) -> &mut Self

pub fn str(&mut self, x: &str) -> &mut Self

Writes a definite length string. Collapses header+data into a single reserve+write.

pub fn big_integer(&mut self, value: &BigInteger) -> &mut Self

Writes a BigInteger using preferred serialization per RFC 8949 §3.4.3.

Values that fit in a CBOR major type 0 or 1 integer are encoded directly (preferred serialization). Larger values use tag 2 (unsigned bignum) or tag 3 (negative bignum). For tag 3, the byte string encodes n where the value is -1 - n.

pub fn blob_bytes(&mut self, data: &[u8]) -> &mut Self

Writes a blob from a byte slice. Collapses header+data into a single reserve+write.

Mirrors Self::str’s slice-input style. Prefer this over Self::blob when the caller already holds a &[u8] (e.g. from a schema-serde ShapeSerializer::write_blob(_, &[u8]) call) — it avoids needing to wrap the bytes in a [Blob] just to satisfy the API.

pub fn blob(&mut self, x: &Blob) -> &mut Self

Writes a blob. Collapses header+data into a single reserve+write.

pub fn array(&mut self, len: usize) -> &mut Self

Writes a fixed length array of given length.

pub fn map(&mut self, len: usize) -> &mut Self

Writes a fixed length map of given length. Used when we know the size in advance, i.e.:

• when a struct has all non-Optional members.
• when serializing union shapes (they can only have one member set).
• when serializing a map shape.

pub fn timestamp(&mut self, x: &DateTime) -> &mut Self

pub fn into_writer(self) -> Vec<u8>

Trait Implementations

impl Clone for Encoder

fn clone(&self) -> Encoder

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Encoder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
