Struct savefile::Canary1

pub struct Canary1 {}

Useful zero-sized marker. It serializes to a magic value, and verifies this value on deserialization. Does not consume memory data structure. Useful to troubleshoot broken Serialize/Deserialize implementations.

Implementations

impl Canary1

pub fn new() -> Canary1

Create a new Canary1 object. Object has no contents.

Trait Implementations

impl Clone for Canary1

fn clone(&self) -> Canary1

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Canary1

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Canary1

fn default() -> Canary1

Returns the “default value” for a type.

impl Deserialize for Canary1

fn deserialize(
    deserializer: &mut Deserializer<'_>
) -> Result<Self, SavefileError>

Deserialize and return an instance of Self from the given deserializer.

impl Introspect for Canary1

fn introspect_value(&self) -> String

Returns the value of the object, excluding children, as a string. Exactly what the value returned here is depends on the type. For some types, like a plain array, there isn’t much of a value, the entire information of object resides in the children. For other cases, like a department in an organisation, it might make sense to have the value be the name, and have all the other properties as children.

fn introspect_child(&self, _index: usize) -> Option<Box<dyn IntrospectItem<'_>>>

Returns an the name and &dyn Introspect for the child with the given index, or if no child with that index exists, None. All the children should be indexed consecutively starting at 0 with no gaps, all though there isn’t really anything stopping the user of the trait to have any arbitrary index strategy, consecutive numbering 0, 1, 2, … etc is strongly encouraged.

fn introspect_len(&self) -> usize

Returns the total number of children. The default implementation calculates this by simply calling introspect_child with higher and higher indexes until it returns None. It gives up if the count reaches 10000. If your type can be bigger and you want to be able to introspect it, override this method.

impl PartialEq<Canary1> for Canary1

fn eq(&self, other: &Canary1) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Serialize for Canary1

fn serialize(
    &self,
    serializer: &mut Serializer<'_>
) -> Result<(), SavefileError>

Serialize self into the given serializer.

impl WithSchema for Canary1

fn schema(_version: u32) -> Schema

Returns a representation of the schema used by this Serialize implementation for the given version.
