Struct wireplumber::spa::json::SpaJsonParser

pub struct SpaJsonParser { /* private fields */ }

Available on crate feature v0_4_8 only.

GLib type: Shared boxed type with reference counted clone semantics.

Implementations

impl SpaJsonParser

pub fn as_ptr(&self) -> *mut WpSpaJsonParser

Return the inner pointer to the underlying C value.

pub unsafe fn from_glib_ptr_borrow<'a>( ptr: *const *const WpSpaJsonParser ) -> &'a Self

Borrows the underlying C value.

impl SpaJsonParser

pub unsafe fn new_array_unchecked(json: &SpaJson) -> SpaJsonParser

pub unsafe fn new_object_unchecked(json: &SpaJson) -> SpaJsonParser

pub fn end(&self)

pub fn boolean(&self) -> Option<bool>

pub fn float(&self) -> Option<f32>

pub fn int(&self) -> Option<i32>

pub fn null(&self) -> bool

pub fn string(&self) -> Option<GString>

impl SpaJsonParser

pub fn new_object(json: &SpaJson) -> SpaJsonParserRef<'_, '_>

pub fn new_array(json: &SpaJson) -> SpaJsonParserRef<'_, '_>

pub fn parse_json(&self) -> Option<SpaJsonRef<'_>>

pub unsafe fn json_unchecked(&self) -> Option<SpaJson>

Gets the SpaJson value from a spa json parser object

Safety

The returned object borrows the underlying parser’s data, which is not tracked by a lifetime.

pub fn json(&self) -> Option<SpaJson>

pub fn parse_end(self) -> Result<(), ParseError>
