Struct Size

pub struct Size { /* private fields */ }

The Size flavor is a measurement flavor, which accumulates the number of bytes needed to serialize the data.

use postcard::{serialize_with_flavor, ser_flavors};

let value = false;
let size = serialize_with_flavor(&value, ser_flavors::Size::default()).unwrap();

assert_eq!(size, 1);

Trait Implementations

impl Default for Size

fn default() -> Size

Returns the “default value” for a type.

impl Flavor for Size

type Output = usize

The Output type is what this storage “resolves” to when the serialization is complete, such as a slice or a Vec of some sort.

fn try_push(&mut self, _b: u8) -> Result<()>

Push a single byte to be modified and/or stored.

fn try_extend(&mut self, b: &[u8]) -> Result<()>

Override this method when you want to customize processing multiple bytes at once, such as copying a slice to the output, rather than iterating over one byte at a time.

fn finalize(self) -> Result<Self::Output>

Finalize the serialization process.
