Fields

initEncoder: Option<unsafe extern "C" fn(encoder: *mut json_encoder, write: json_writeFunc, userdata: *mut c_void, pretty: c_int)>

void playdate->json->initEncoder(json_encoder* encoder, writeFunc* write, void* userdata, int pretty);

Populates the given json_encoder encoder with the functions necessary to encode arbitrary data into a JSON string. userdata is passed as the first argument of the given writeFunc write. When pretty is 1 the string is written with human-readable formatting.

decode: Option<unsafe extern "C" fn(functions: *mut json_decoder, reader: json_reader, outval: *mut json_value) -> c_int>

int playdate->json->decode(struct json_decoder* decoder, json_reader reader, json_value* outval);

Equivalent to playdate.json.decode() in the Lua API.

decodeString: Option<unsafe extern "C" fn(functions: *mut json_decoder, jsonString: *const c_char, outval: *mut json_value) -> c_int>

int playdate->json->decodeString(struct json_decoder* decoder, const char* jsonString, json_value* outval);

Decodes a JSON file or string with the given decoder. An instance of json_decoder must implement decodeError. The remaining functions are optional although you’ll probably want to implement at least didDecodeTableValue and didDecodeArrayValue. The outval pointer, if set, contains the value retured from the top-level didDecodeSublist callback.

Trait Implementations

impl Clone for playdate_json

fn clone(&self) -> playdate_json

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for playdate_json

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

Formats the value using the given formatter.

impl Default for playdate_json

fn default() -> playdate_json

Returns the “default value” for a type.

impl Hash for playdate_json

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given [Hasher].

impl Ord for playdate_json

fn cmp(&self, other: &playdate_json) -> Ordering

This method returns an [Ordering] between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for playdate_json

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for playdate_json

fn partial_cmp(&self, other: &playdate_json) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Copy for playdate_json

impl Eq for playdate_json

impl StructuralPartialEq for playdate_json

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
