Struct opencv :: dnn :: LayerFactory Copy item path

impl LayerFactory

pub fn register_layer( typ: &str, constructor: LayerFactory_Constructor ) -> Result<()>

Registers the layer class with typename @p type and specified @p constructor. Thread-safe.

pub fn unregister_layer(typ: &str) -> Result<()>

Unregisters registered layer with specified type name. Thread-safe.

pub fn is_layer_registered(typ: &str) -> Result<bool>

Check if layer is registered.

pub fn create_layer_instance( typ: &str, params: &mut impl LayerParamsTrait ) -> Result<Ptr<Layer>>

Creates instance of registered layer.

§Parameters

type: type name of creating layer.
params: parameters which will be used for layer initialization.

Note: Thread-safe.

Blanket Implementations§

impl<T> Any for T
where T: 'static + ?Sized,

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

impl<T> Borrow<T> for T
where T: ?Sized,

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

impl<T> BorrowMut<T> for T
where T: ?Sized,

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

impl<T> From<T> for T

fn from(t: T) -> T

Returns the argument unchanged.

impl<T, U> Into for T
where U: From<T>,

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

impl<Mat> ModifyInplace for Mat
where Mat: Boxed,

unsafe fn modify_inplace<Res>( &mut self, f: impl FnOnce(&Mat, &mut Mat) -> Res ) -> Res

Helper function to call OpenCV functions that allow in-place modification of a Mat or another similar object. By passing a mutable reference to the Mat to this function your closure will get called with the read reference and a write references to the same Mat. This is of course unsafe as it breaks the Rust aliasing rules, but it might be useful for some performance sensitive operations. One example of an OpenCV function that allows such in-place modification is imgproc::threshold. Read more

impl<T, U> TryFrom for T
where U: Into<T>,

type Error = Infallible

The type returned in the event of a conversion error.

fn try_from(value: U) -> Result<T, <T as TryFrom>::Error>

Performs the conversion.

impl<T, U> TryInto for T
where U: TryFrom<T>,

type Error = >::Error

The type returned in the event of a conversion error.
