Struct postcard::ser_flavors::HVec

pub struct HVec<const B: usize> { /* private fields */ }

The HVec flavor is a wrapper type around a heapless::Vec. This is a stack allocated data structure, with a fixed maximum size and variable amount of contents.

Implementations

impl<const B: usize> HVec<B>

pub fn new() -> Self

Create a new, currently empty, heapless::Vec to be used for storing serialized output data.

Trait Implementations

impl<const B: usize> Default for HVec<B>

fn default() -> HVec<B>

Returns the “default value” for a type.

impl<const B: usize> Flavor for HVec<B>

type Output = Vec<u8, B>

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_extend(&mut self, data: &[u8]) -> Result<()>

The try_extend() trait method can be implemented when there is a more efficient way of processing multiple bytes at once, such as copying a slice to the output, rather than iterating over one byte at a time.

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

The try_push() trait method can be used to push a single byte to be modified and/or stored

fn finalize(self) -> Result<Vec<u8, B>>

Finalize the serialization process

impl<const B: usize> Index<usize> for HVec<B>

type Output = u8

The returned type after indexing.

fn index(&self, idx: usize) -> &u8

Performs the indexing (container[index]) operation.

impl<const B: usize> IndexMut<usize> for HVec<B>

fn index_mut(&mut self, idx: usize) -> &mut u8

Performs the mutable indexing (container[index]) operation.
