Struct postcard::ser_flavors::AllocVec

source ·
pub struct AllocVec { /* private fields */ }
Expand description

The AllocVec flavor is a wrapper type around an alloc::vec::Vec.

This type is only available when the (non-default) alloc feature is active

Implementations§

source§

impl AllocVec

source

pub fn new() -> Self

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

Trait Implementations§

source§

impl Default for AllocVec

source§

fn default() -> AllocVec

Returns the “default value” for a type. Read more
source§

impl Flavor for AllocVec

source§

type Output = Vec<u8>

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

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.
source§

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
source§

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

Finalize the serialization process
source§

impl Index<usize> for AllocVec

source§

type Output = u8

The returned type after indexing.

source§
