Struct zng_app :: render :: FrameValueKey Copy item path

impl<T> FrameValueKey<T>

pub fn new_unique() -> Self

Generates a new unique ID.

pub fn to_wr(self) -> FrameValueId

To view key.

pub fn to_wr_child(self, child_index: u32) -> FrameValueId

To view key with an extra index modifier.

pub fn bind(self, value: T, animating: bool) -> FrameValue<T>

Create a binding with this key.

The animating flag controls if the binding will propagate to webrender, if true webrender frame updates are generated for

pub fn bind_child( self, child_index: u32, value: T, animating: bool, ) -> FrameValue<T>

Like bind but the key is modified to include the child_index.

pub fn update(self, value: T, animating: bool) -> FrameValueUpdate<T>

Create a value update with this key.

pub fn update_child( self, child_index: u32, value: T, animating: bool, ) -> FrameValueUpdate<T>

Like update but the key is modified to include the child_index.

pub fn bind_var<VT: VarValue>( self, var: &impl Var<VT>, map: impl FnOnce(&VT) -> T, ) -> FrameValue<T>

Create a binding with this key and var.

The map must produce a copy or clone of the frame value.

pub fn bind_var_child<VT: VarValue>( self, child_index: u32, var: &impl Var<VT>, map: impl FnOnce(&VT) -> T, ) -> FrameValue<T>

Like bind_var but the key is modified to include the child_index.

pub fn bind_var_mapped<VT: VarValue>( &self, var: &impl Var<VT>, value: T, ) -> FrameValue<T>

Create a binding with this key, var and already mapped value.

pub fn bind_var_mapped_child<VT: VarValue>( &self, child_index: u32, var: &impl Var<VT>, value: T, ) -> FrameValue<T>

Like bind_var_mapped but the key is modified to include the child_index.

pub fn update_var<VT: VarValue>( self, var: &impl Var<VT>, map: impl FnOnce(&VT) -> T, ) -> Option<FrameValueUpdate<T>>

Create a value update with this key and var.

pub fn update_var_child<VT: VarValue>( self, child_index: u32, var: &impl Var<VT>, map: impl FnOnce(&VT) -> T, ) -> Option<FrameValueUpdate<T>>

Like update_var but the key is modified to include the child_index.

pub fn update_var_mapped<VT: VarValue>( self, var: &impl Var<VT>, value: T, ) -> Option<FrameValueUpdate<T>>

Create a value update with this key, var and already mapped value.

pub fn update_var_mapped_child<VT: VarValue>( self, child_index: u32, var: &impl Var<VT>, value: T, ) -> Option<FrameValueUpdate<T>>

Like update_var_mapped but the key is modified to include the child_index.
