Struct JanssonValue 

pub struct JanssonValue { /* private fields */ }

A safe wrapper for a Jansson JSON value. Automatically increases and decreases the refcount of the underlying value when cloned/dropped.

Implementations

impl JanssonValue

pub unsafe fn from_and_incref(ptr: *mut RawJanssonValue) -> Option<Self>

Creates a JanssonValue owning the given raw pointer, incrementing the reference count.

pub unsafe fn from_raw(ptr: *mut RawJanssonValue) -> Option<Self>

Creates a JanssonValue owning the given raw pointer. Does not increment the reference count, but the JanssonValue’s destructor will decrement the reference count.

pub fn into_raw(self) -> *mut RawJanssonValue

Transfers ownership of this value to this pointer. The consumer of the pointer is responsible for calling json_decref on it later.

pub fn as_mut_ref(&mut self) -> &mut RawJanssonValue

Gets the reference backing this value without taking ownership.

pub fn from_str( input: &str, decoding_flags: JanssonDecodingFlags, ) -> Result<Self, Box<dyn Error + Send + Sync>>

Decodes a JSON string slice into a Jansson value, returning an error if decoding fails.

pub fn from_cstr( input: &CStr, decoding_flags: JanssonDecodingFlags, ) -> Result<Self, Box<dyn Error + Send + Sync>>

Decodes a JSON C-style string into a Jansson value, returning an error if decoding fails.

pub fn to_libcstring(&self, encoding_flags: JanssonEncodingFlags) -> LibcString

Encodes this Jansson value as a JSON owned C-style string.

Trait Implementations

impl Clone for JanssonValue

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JanssonValue

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

Formats the value using the given formatter.

impl Deref for JanssonValue

type Target = json_t

The resulting type after dereferencing.

fn deref(&self) -> &RawJanssonValue

Dereferences the value.

impl Drop for JanssonValue

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
