Struct Dict

pub struct Dict { /* private fields */ }

This class implements name-value dictionary, values are instances of DictValue.

Implementations

impl Dict

pub fn default() -> Dict

Creates a default instance of the class by calling the default constructor

Trait Implementations

impl Boxed for Dict

unsafe fn from_raw(ptr: <Dict as OpenCVFromExtern>::ExternReceive) -> Self

Wrap the specified raw pointer

fn into_raw(self) -> <Dict as OpenCVTypeExternContainer>::ExternSendMut

Return the underlying raw pointer while consuming this wrapper.

fn as_raw(&self) -> <Dict as OpenCVTypeExternContainer>::ExternSend

Return the underlying raw pointer.

fn as_raw_mut(&mut self) -> <Dict as OpenCVTypeExternContainer>::ExternSendMut

impl Debug for Dict

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

Formats the value using the given formatter.

impl Default for Dict

fn default() -> Self

Forwards to infallible Self::default()

impl DictTrait for Dict

fn as_raw_mut_Dict(&mut self) -> *mut c_void

unsafe fn ptr_mut(&mut self, key: &str) -> Result<DictValue>

If the @p key in the dictionary then returns pointer to its value, else returns NULL.

fn set_str(&mut self, key: &str, value: &str) -> Result<String>

Sets new @p value for the @p key, or adds new key-value pair into the dictionary.

fn set( &mut self, key: &str, value: &impl DictValueTraitConst, ) -> Result<DictValue>

Sets new @p value for the @p key, or adds new key-value pair into the dictionary.

fn set_f64(&mut self, key: &str, value: &f64) -> Result<f64>

Sets new @p value for the @p key, or adds new key-value pair into the dictionary.

fn set_i64(&mut self, key: &str, value: &i64) -> Result<i64>

Sets new @p value for the @p key, or adds new key-value pair into the dictionary.

fn erase(&mut self, key: &str) -> Result<()>

Erase @p key from the dictionary.

impl DictTraitConst for Dict

fn as_raw_Dict(&self) -> *const c_void

fn has(&self, key: &str) -> Result<bool>

Checks a presence of the @p key in the dictionary.

unsafe fn ptr(&self, key: &str) -> Result<DictValue>

If the @p key in the dictionary then returns pointer to its value, else returns NULL.

fn get(&self, key: &str) -> Result<DictValue>

If the @p key in the dictionary then returns its value, else an error will be generated.

impl Drop for Dict

fn drop(&mut self)

Executes the destructor for this type.

impl From<LayerParams> for Dict

fn from(s: LayerParams) -> Self

Converts to this type from the input type.
