Struct serde_stacker::Serializer

pub struct Serializer<S> {
    pub ser: S,
    pub red_zone: usize,
    pub stack_size: usize,
}

Serializer adapter that avoids stack overflows by dynamically growing the stack.

At each level of nested serialization, the adapter will check whether it is within red_zone bytes of the end of the stack. If so, it will allocate a new stack of size stack_size on which to continue deserialization.

Fields

ser: S

red_zone: usize

stack_size: usize

Implementations

impl<S> Serializer<S>

pub fn new(serializer: S) -> Self

Build a serializer adapter with reasonable default red_zone (64 KB) and stack_size (2 MB).

Trait Implementations

impl<S> Serializer for Serializer<S> where
    S: Serializer, 

type Ok = S::Ok

The output type produced by this Serializer during successful serialization. Most serializers that produce text or binary output should set Ok = () and serialize into an [io::Write] or buffer contained within the Serializer instance. Serializers that build in-memory data structures may be simplified by using Ok to propagate the data structure around.

type Error = S::Error

The error type when some error occurs during serialization.
