Struct Deserializer

pub struct Deserializer<'de> { /* private fields */ }

Deserializer struct to deserialize a JSON

Implementations

impl<'de> Deserializer<'de>

pub fn algorithm() -> Implementation

returns the algorithm / architecture used by the deserializer

impl<'de> Deserializer<'de>

pub fn into_tape(self) -> Tape<'de>

Extracts the tape from the Deserializer

pub fn as_value(&self) -> Value<'_, 'de>

Gives a Value view of the tape in the Deserializer

pub fn restart(&mut self)

Resets the Deserializer tape index to 0

pub fn from_slice(input: &'de mut [u8]) -> Result<Self>

Creates a serializer from a mutable slice of bytes

Errors

Will return Err if s is invalid JSON.

pub fn from_slice_with_buffers( input: &'de mut [u8], buffer: &mut Buffers, ) -> Result<Self>

Creates a serializer from a mutable slice of bytes using a temporary buffer for strings for them to be copied in and out if needed

Errors

Will return Err if s is invalid JSON.

pub unsafe fn next_(&mut self) -> Node<'de>

Same as next() but we pull out the check so we don’t need to stry every time. Use this only if you know the next element exists!

Safety

This function is not safe to use, it is meant for internal use where it’s know the tape isn’t finished.

Trait Implementations
